QUIC (the basis for HTTP/3) is basically the spiritual successor to SCTP, except with TLS baked in, so compared with SCTP+DTLS, connection establishment requires significantly fewer roundtrips (0 round trips for session resumption, 1 roundtrip at worst, compared to 4 or so for DTLS).
Unfortunately, most computers only pass TCP and UDP (Windows and middleboxes). So, protocol evolution is a dead end.
Thus have to piggyback on what computers will let through--so you're stuck with creating an HTTP flavor of TCP.
