You left out the very important detail that practically speaking, your content also needs to be hosted on Google's CDN if you want to get any of the benefits that content creators are likely to care about (being boosted in SERPs).

I don't know how I missed that, I must have skimmed around that point, yes that is very important. Looking through the wiki page I found it quite easily, but it doesn't stick out as much on the ampproject official page.

Hosting on Google’s CDN is not a requirement. There are third party AMP-caches, for example Cloudflare runs one.

It would help if the anti-AMP hysteria stays to the facts.
