If Google really disliked slow and bloated sites they could apply a search penalty for page load and weight. Promoting amp is promoting Google not solving the problem of heavy sites.
It’s Official: Google Now Counts Site Speed As A Ranking Factor

Starting in July 2018, Google will finally use mobile page speed as a ranking in their mobile search results.

Google did just add a "Mobile Speed Score" to each URL in Adwords with a 1-10 scale of unknown composition/weighting that media folks and marketing managers can see, but developers can't really dig into (other than using...Google's Lighthouse for correlations). https://www.searchenginejournal.com/google-introduces-the-mo...
Oh, yeah, it also upsells AMP. Even if you're opposed to or otherwise not going to adopt it as an engineering team, they're clearly going after the non-technical stakeholders to make it happen.
So I stand by my first comment. If they cared there would be a Penguin style update to penalise page excess like they have in the past for poor quality link farms etc.
