Google also has additional power by simply not implementing things introduced by WHATWG participants. Case in point: the menu/menuitem elements which would have provided scriptless interaction in a limited way (removed from W3C HTML 5.2). Any small attempt to make the web more declarative by extending HTML is doomed since not essential because it can be implemented using JS.

WHATWG's specification process, putting the world's main communication medium into the hands of browser vendors with an interest to eliminate competition and define entirely new Turing runtimes (WASM), and advertisers who turn around and create competing mechanisms (AMP), then not actually ever delivering a standard (the "living standard" nonsense) is broken, and has been for a long time.
