Sorry if this distracts from the topic, but one of the biggest reasons I, and a few people I know, don't like AMP is that - this will sound trivial - but they're a real annoyance when you want to cut and paste a link into an email or a text message when you're on a phone. I'm not going to screw around with finding a share button or what have you on a mobile site, nobody knows what JS is behind those.

So, lack of UX with the links.
