(Repeating and expanding my comment on #1269 to the list) +1 to CID rotation being pointless if we don't do this. However, this seems dangerous if not done carefully, and it links CID rotation rate to the maximum usable UDP port consumption rate, which is (most probably) widely variable across access networks and (AFAICT) largely unknown in the literature. We have anecdata here, and we need data. Note that QUIC presently doesn't have an advisory on-path state clearance signal (we hsd discussed this as a signal bound to public reset in #20, but it morphed into Stateless Reset, which has completely different semantics), which means that there is neither a present nor yet a potential future method to reduce the NAT state load this will generate. I'd feel a lot less apprehensive about this if there were an advisory, integrity-protected signal meant for path consumption to clear state for a path. Of course it wouldn't be used at all on day one, but the tradeoff it presents is "hey, this is QUIC, it will burn through your UDP port state faster than any other UDP protocol and multiplicatively faster than TCP; but hey look, you can clear state when you see this path-verifiable singal to reduce the impact this has."
