Google could use dns-prefetch to tell the browser to to pre-fetch the DNS records for the domains in the top search results... That would decrease page load time up to one second! (the caching being the main advantage of AMP - it would make AMP unnecessary) Really, why are not browsers pre-fetching DNS records automatically for all links visible on the screen!?

Tracking potential and waste of network and DNS server resources.

  For HTTPS sites Google could be trusted with providing the IP for the domain, then no extra lookup would be needed, and there would be even less tracking (by the ISP). DNS lookups is however very cheap due to several layers of caching (browser, OS, router, ISP, etc).
