> No, because any browser can decide to ship a feature that it thinks is worthwhile.
Yes, yes they can. They don't get to call it standard or essential. And Chrome-shilling sites like the pwa.gripe and a slew of others don't get to call those features "essential standards of the web".
> No single company in control.
That is literally not how standards work in the browser world by literal agreement of all browser vendors.
We literally lived through this with IE pushing its own non-standard features and calling it a day. Hence the whole "let's reach a consensus, and have several independent implementations of a feature before calling it a standard".
And if "no single company is in control", why then you're so enthusiastically pushing for a Google's full control of the web?
