I don't understand. So now the URL bar won't always show where the page was actually loaded from? It could show example.com but really be loaded from Google'S AMP servers? If I'm reading this right, I find it very sad.
And AMP is planning to use cryptographic signing so that the browser can verify that the CDN didn't tamper with the page.
In this future, it seems like the content will be signed with Apples TLS certificate/key and then the content can be distributed by anyone.
This could open the doors for a more distributed web too :)
It was not presented as a new and fairly dramatically different way of distributing content on the web, it was presented as a way to get around showing the URL in response to pushback from the web community.
I think if this announcement were written differently, I would've come away with a much better impression of the whole thing.
But the new door this opens in terms of content distribution are very interesting.
Shared caches might be a thing again... Who knows :)
