Re: Since google pretty much control the browser market
Was just about to post something similar. What happens if Firefox and Chrome, which make up like 95%+ of the browser market -- including Chromium based browsers -- just refuse to support it? And if Apple decides not to add it to Safari in iOS/iPadOS, that probably brings the total up to around 99% of all browser users. It may technically be part of the spec, but no one can do anything with it unless they go out of their way to use a browser that supports it, and everyone else visiting that specific site also goes out of their way to find a supporting browser.
Then either the W3C goes back and addresses the concerns of the browser makers or just accepts that their pet project is stillborn.
