I agree with what you have to say, but just want to respond to last second paragraph: QUIC basically is a new version of TCP. Yeah, it's based on UDP, but, that is just an implementation detail. If it weren't for various poorly behaved middleboxes, QUIC could just sit on top of IP like TCP does. But, it can't - so we hold our noses and put it on top of UDP and we end up with something that actually works.
