In the evergreen (and generally broadly much better) browser age this is an assumption / concern that I think could really use some reconsideration, lol.

Maybe once we didn't dare surmount the challenge, but today, the landscape is a lot better (and a lot less chaotic) and while yeah it sort of sucks in some annoying ongoing ways I can't imagine every org is going to find this some insurmountable difficult strenuous activity. Like, get good.

The anti-will against doing this drives people away from the web as platform.
