AMP improved pages mostly by forcing publishers to start from scratch. They needed to get something out the door, so they made a minimum viable version, without all the cruft and trackers. Then they started cramming more and more of that into the AMP version, despite AMP making that hard. Giving better placement for the main page version won't be as effective, because it doesn't force them to start from scratch. At best, we'll see some incremental improvements. I've seen an ad that managed to consume so many resources that Chrome blocked it. Reducing the threshold for that blocking would be much more effective.
