> Except AMP sites usually aren't faster. They just get preloaded[0]. If google preloaded non-AMP sites (which is technically feasible, there has been browser extensions doing this since ages ago), they too would load "faster", fancy that!

This is not feasible in a security conscious way. Preloading leaks metadata (at a minimum things like IP address, and probably much more for a useful implementation) to third party hosts without any user interaction.

Even without preloading, as I understand it, amp is still faster than your "average" site since it enforces decent performance hygiene. Yes, performance conscious owners can create slightly faster sites, but most don't. The 0.0s load times for preloaded sites and potential to cache is just butter for an end user.
