Very much appreciate the work What's AMPs goal here, is it to have untrusted third parties write their own UI's, but still run that whole site on the google domain? I hate to be cynical but if so that's the same old walled garden approach to further centralize the web It would be far easier to just rate the page performance specs while indexing, and provide a free google CDN for heavy assets to protect privacy so they can preload most of them This does look exciting for things like embedding small components from untrusted third parties into the middle of an article or page though
