Personally I think just leave it to users to vote with their feet. If I think a site is too slow to load or too slow to use, I'll stop using it. If I'm happy to wait for 10Mb of js to run a web app, then let me.
YES - I hate Google, their AMP team, or anyone else trying to tell us how to "fix" the web.
It used to be innocuous when Google had 20% browser market share, but now they act like they own how users should experience the web. Like the uBlock origin guy said... if Chromium keeps heading down this path it should no longer be called a "user-agent" because it's no longer acting on behalf of users.
