Ship has already sailed, it's called DoH. Please note, that it is to make your DNS safer and has absolutely nothing to do with removing your ability to resolve DNS in whatever way you want to(cough adblock cough).

I guess I just missed that?! I'm running a mix of Adguard and nextdns blockers on some of my mobile devices, and both are apparently handling the DoH issue for you; by just blanket blocking the resolvers and/or ports, to force a fallback.... I need a Beer.
