@udon @Misato I agree with the XHTML, CSS, HTML5, and JS parts, though I think that JS should be restricted to just vanilla JS, so none of that ECMA bullshit.
As for WebRTC, WebGL, and WebASSembly, that's pure bloat that should have never been used in the browser in the first place.
If you need to play gaymes, play them on the OS directly.
If you need to run non-browser applications, run them directly on the OS.
If you need video calling, well there used to be native apps who could do that, but nowadays it's all Electron crap (or Jami that always crashes and never works anyway)...
