Or when you click in on some mobile and the whole url disappears and you just wanted to change part of the url.

AMP might be the thing that actually brings anti-trust, so not needed and very anti-competitive using their monopoly position to stifle competition and innovation rather than extend innovation and compete on product. Google should reward fast sites not band-aid it with an anti-competitive AMP. AMP also creates lots more work for content companies and it is only useful for Google. Essentially content companies are doing Google's work for them.
McKinsey and the management consultants have taken over large swaths of Google with stuff like this and AMP.
Here's hoping some pirate product people/engineers put up a flag and start returning to product over management metrics.
