I'll take the unpopular opinion from the end-user's perspective here: When I was recently traveling and only had access to an overused satellite connection and my phone, the only pages that were even remotely usable were AMP pages. Given that I can definitely see the niche that they're trying to fix, not really to help us with a blazing fast, low latency 5G connection on a new top end phone.
Sure you could argue that companies can create a similar experience with their web sites but let's be honest that only few would invest the time for it, and then they'd still have a discoverability problem.
AMP might still be somewhat flawed, but it's a centralized step in the right direction, and it does sound like the team is open to feedback, so I'll give them points there even if they haven't made it perfect yet.
