We deliberately did not do either: * make QUIC distinguishable * make QUIC indistinguishable We might have been close on the second, but that is simply a consequence of other design pressures (efficiency, security, privacy). > <<Management of QUIC traffic can never be reliable, and if it becomes so > over time, then the QUIC wire image would be forced to evolve.

As before, QUIC is not deliberately anti-management, it just has a limited surface area by which it might be managed (like the spin bit). That said, your heuristic here is more or less accurate, though I'm not sure that you can say that definitively, it's likely what will happen. -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
