HTTP/2 is a clear win over HTTP/1 and was the easiest first step, but as you've noted there's substantial interest in running HTTP/2 over better-than-TCP transport (UDP being the only practical alternative in the near term, what with middleboxes being so horribly omnipresent).

I think I was actually thinking of the somewhat confusingly-named "QUIC Crypto", which is actually dead, and we should either use TLS 1.3, or, as QUIC apparently does now, DTLS.

Really?  How so?
