One of the regular complaints I've pushed against AMP is that it's a hamfisted way to address page speed. Search placement should be determined by generic speed tests, not by forcing developers to use Google's technology. This looks to me like a positive effort. I'm not thrilled with overlays like this, and I'm not thrilled with baking this kind of stuff into the browser. It feels over-engineered and weird. But, I think it's a better direction than AMP. There are a lot of ways this could go bad, but very cautious thumbs up from me.
