Number 8 is absurd.

> browsers and big platforms like Google Search today have no mechanism to prove that your site is indeed fast and user friendly. So by choosing to do it all on your own, you might create a super fast site, but there’s no way to know for sure. This validation aspect of AMP is what makes it so attractive for 3p platforms.

Ok, so... Google's been making a business saying your website IS or ISN'T fast enough for mobile. (I have 2 old client websites that Google yells at me weekly about 'not being mobile optimized' (thanks mom, I know). Why all of a sudden can they NOT PROVE your site is fast enough? if they've been claiming to say its fast or not fast all this time?
