I see where you are going, but what if my website is updated?Is the archive at address _myurl_ invalidated, or is there a new address where it can be found? I am thinking of reproducible URLs for academic references or qualified procedures, for example, which might or might not matter in the intended use case.
Could there be net-neutrality-like questions in all this as well?
But AMP is a much narrower technology, I’d imagine only Google would be able to impersonate other websites, essentially centralised as you say. The generic idea would just be a distraction to push AMP.
Everything would be so much better if the original websites were not so overloaded with trackers, ads and banners, then there would be no need for these “accelerated” versions.
