I am deeply concerned by the onrushing move to udp for QUIC, with udp the former province of voip, gaming, request/response and videoconferencing traffic. I certainly see natted udp ports get used up rapidly by various tools, and also see timeouts for reuse often below 30sec. IMHO, QUIC should

Periodically I still do some work on routing protocols. 12? years ago I had kind of given up on ospf and isis, and picked the babel protocol as an IGP for meshy networks because I felt link-state had gone as far as it could and somehow unifying BGP DV with an IGP that was also DV (distance vector)
