The README is a bit confusing as to the purpose of the extension until you read the linked site explaining what AMP is: https://www.ampproject.org/. This tech post also helps a bit: https://www.ampproject.org/how-it-works/

My first impression is that the whole thing is kind of a gross hack on top of HTML. I get that there's a lot of work you don't need to do when you do it this way, but this likely won't survive long.

We have a perfectly good container format called Atom that could have done the job here. Instead of hacking and slashing at HTML, why not define an AMP markup language and well-specify the transformation to HTML?
