Otherwise you get Internet Explorer, in reverse: https://www.quirksmode.org/blog/archives/2021/08/breaking_th...
Chrome literally doesn't even bother pretending that many of their proposals are more than some scribbles in spec-adjacent format. E.g. a spec for WebHID that other browsers could implement was just dumped into the repo after Chrome shipped it.
Constructable Stylesheets had both a badly named API and a trivially triggered race condition. Shipped in Chrome in the middle of discussion because Google-developed lit "needed" it.
And so on and so forth.
The problem with all of these new specifications is that Google can’t convince anybody to do this, no matter how much money they throw at them. That’s not an Apple veto stopping these things from becoming standards, that’s Google pushing shitty specs.
We've kinda come full circle. Web standards were made to prevent what happened when Internet Explorer ruled the world but now a corporation has near-monopoly browser share and is driving the web standards themselves
