At least there was a distinction between web of documents (WWW) and shipped apps with custom canvas. Rendering apps with web’s DOM is stupid. It makes websites a mess and relies on everyone using the same monoculture of browsers (like we now have Chromium, WebKit and Gecko, all nearly identical).
If browser does not support one feature (like CSS’s transform), the whole house of cards breaks. It’s like making ASCII art in notepad and then expecting everyone to use the same notepad app with the same font and style, to not break our art proportions.
We need to split web into websites and webapps, with webapps being browser dependent or full custom canvases and websites being immutable human-readable and editable format.
All the things you named are things that I think should largely be kept the same. Having them be identical or near enough to it is the goal I’m trying to achieve.
Things that should be kept different are things like Manifest V2’s deprecation and WEI. Things that are, by their nature, comparatively surface level and separate.
So you just want to give Google total control over the core web platform technologies and other browsers will just accept what Google decided. That’s exactly the state I’d like to avoid.
