The last time we went to year-round DST, we stopped almost immediately because people experienced what winter DST was actually like and went "wait, this sucks."
I always find it strange how particular people are about the numbers attached a purely astronomical phenomena(myself included, but I am pretty hard in the "let the sun figure it out camp"). If they want more "daylight" hours then get up at a time to enjoy them. But people would rather bend over backwards fiddling with the numbers as if that is going to change how long a day is.
Does it become Friday at dawn, at sunset, at noon, or at midnight?
This is all convention and not something that can be decided objectively.
I do not care if the sun is up as I shuffle groggily into the building. I don't think I'm alone.
After college I moved from the far western edge of one timezone to the far eastern edge of another zone. I grew up with 5-5:30pm sunsets in winter, and now I live with 4-4:30pm sunsets. I moved here 25 years ago, and every single year when November/December come around and I get those early sunsets I hate it. It's one of the reasons I'd like to move away from here.
I know it's just one person's opinion, but to me those extremely early sunsets in the middle of winter are a huge quality of life reduction.
I believe part of the problem is that if you're in the middle or western edge of your zone, the winter sunsets aren't so bad. I suspect a lot of people who would prefer DST year round live on the eastern edge.
Farmers have to wake up early because their animals wake up at sunrise and some tasks are best performed at that time. So they wake up before sunrise regardless of the clock time.
Human, like farm animals, are better off if they wake up at sunrise and go to sleep in full dark. At the equator that's easy, wake at 6, bed at 10PM. And standard work hours are 7-3 or 8-4.
I think this would make way more sense, when they say the Olympic Opening Ceremony start at 18:00, its 18:00 for everyone around the world. No one as to work out which TZ Italy is in or scheduling meetings with Tech Support in far flung locales does not require knowing IST is how far ahead or behind.
> He promoted worldwide standard time zones, a prime meridian, and use of the 24-hour clock as key elements to communicating the accurate time, all of which influenced the creation of Coordinated Universal Time.
The one bit where this would be problematic would be "what day is it?" When does today become tomorrow?
There are a lot of systems that we've built that depend on that distinction. Things like business days and running end of day so that everything that happens on March 2nd is logged as March 2nd. I've encountered fun with Black Friday sales where the store is open over the midnight boundary and the backend system really wants today to be today rather than yesterday (sometimes this has involved unplugging a register from the network so that it doesn't run end of day, running EOD on the store systems, and then plugging the register back in after it completes and then running a reconciliation.).
Other than that particular mess of banks and businesses... yea, running everything on UTC would be something nice in today's world.

This is also kind of what happens in China (with a complicated history). https://github.com/eggert/tz/blob/main/asia#L272
https://en.wikipedia.org/wiki/Time_in_China UTC+08:00 is observed throughout the country even though it spans about 60° of longitude.

Aside on the "changing clocks" and realizing my flexible schedule privilege at a company I worked at I switched my schedule from 8-4 to 9-5 with the change in daylight savings so that I maintained a consistent "this is the hour I wake up".
Yes.
> and that we should all just use UTC and ...
No. that does not follow. Abstraction is useful. Having commonly understood terms (in this case hours of the day) that share certain traits regardless of where you happen to be in the world facilitates communication.
Now, standard business hours (9-5 or whatever) were probably chosen for working well in the circumstances where they became standard, and it might be interesting to watch for whether tweaking the clocks leads to tweaking the nominal time of things...
But also, all the opinion polling (business and individual) was like over 90% in favour of year-round daylight time, so here we are.
How is transitioning permanently to one easier than transitioning permanently to the other?
How to transition to permanent DST: wait until we are in DST and then stop switching.
How to transition to permanent Standard time: wait until we are in standard time and then stop switching.
It's a 4 month-hour difference over the year, instead of an 8 month-hour difference.
Personally, I'd prefer standard time, but having all days be 86400 seconds is a pretty great improvement over status quo. I find what most people really would like to change is the amount of time with sunlight in the winter, especially the more north they live... but changing the clock doesn't change the number of hours of sunlight; Vancouver, BC just doesn't have much sunlight in the winter.
The reason is that with standard time, solar noon coincides with local noon, so the day is approximately symmetric about noon, not regarding atmospheric refraction lengthening the day. It wasn't done on a whim.
Why? because they decided to be on the same timezone as our eastern neighbors in Europe. The eastern part of Polonia is on the same timezone and probably have probably the opposite with much much earlier lunch and dinner than we do.

The old borders aligned with the sun a lot more, so we can blame that on WW2 as well.
And yes, we could have all the schools and everything else open later in the winter than the rest of the year, but it turns out it's easier to change the clocks.
Absolutely not. It was a compromise tempered by practical and political considerations.
Alas, I don't see my preferred method of changing the clock by 10 minutes every month taking hold. Basically ever. :D
I also don't think this is nearly as important for places that are not further away from the equator. If you are on the equator, you are almost certainly fine with no change throughout the year.
I want to be able to say I sleep from 0 to 3 hours or 30 percent of the day.
And we rethought it yet again, should we go on the time standard (DST) that we're already on for ~65% of the year, or the one we're on for ~35% the year.
It should be pretty obvious why DST is the new winner, it's the current standard.
If you want to go with what was settled long ago, that would probably be a return to each town observing its own time based on local solar noon, which would be pretty annoying.
