What happens if you just focus in the address bar and hit enter or hit the reload button? Either result, the user won’t actually be sure where it’s loaded from.

AMP is an objectively bad thing, designed to further strengthen googles control over the web.

I’ll be encouraging my customers who currently do or may have used cloudflare to use alternative solutions from now on.

Edit: removed weird extraneous “that”

How does the browser know to grab the real page or the amp version? I never want to load an amp page in my browser and out of respect for others privacy I never want to share a link to an AMP page. How can I do this with the new proposal?

So in order to get to a non-AMP version of the page, you have to duplicate the tab? The content will be different but the URLs will be the same? How is any ordinary web user supposed to understand this?

Correct, it's essentially the same as it is now, but easier as you don't have to worry about removing the "google.com/amp" prefix.
