Nobody is going to win over browsers with an opinionated batteries included application framework.
I wouldn't say that any of them were particularly "batteries included", either. Flash was probably closest but still left a lot of legwork to the developer.
There are hundreds of browsers these days, you shouldn't have a hard time finding one that fits your needs.
I'm not sure what you mean given that JS and CSS account for at least half of the kitchen sink.
Hell, wasn't there someone that implemented an entire OS stack in CSS?
The existence of elinks which is marginally useful on the modern web doesn't make the cut nor do tools to un-shitify the existing web.
There is no way not to send information back to the host.
Merely requesting a document is sending information to a host.
I don't mean all the extra metadata in the request header or cookies let alone the all the functionality in javascript or wasm or plugins, I mean nothing more than the name of a document, the bare minimum info required to get something you want it to give you.
If you want me to give you an apple, at the very least you have to tell me to give you an apple.
It all started with nothing more than that bare function, and we don't even want any less than that.
You do need to be able to request a document, and there is no way for a client to prevent a server from replacing a simple static document with a cgi script that performs logic based on the file name. Even without the extra cgi query string, just a document name itself.
But about query strings... there is no way to make a typical query string illegal anyway. It's all just strings of characters. Anything can be encoded within anything else. If you try to make a system that makes say the & and ? characters illegal, that accomplishes exactly nothing.
You just pick any sequence of legal charaters and interpret those in place of the old ? and &, and = and % and anything else you want that doesn't look like part of a legal file or document name.
The special encoded charaters can even be different for each document, even different for each request. It's not possible to make a rule that prevents it.
Let's go totally off the deep end and say that you aren't even allowed to make up your own file names any more. All documents on earth have known names in a whitelist. You can't encode anything because every valid document has a known name and known content. Then you can still encode information in the pattern of access. Requesting file A followed by file F means something extra to you and the server.
But don't take my naysayer defeatist lack of imagination word for it. Go ahead and try to actually explain how the system should work.

It's about as stripped-down as the web can get.
