Just a heads-up to the DPRIVE WG and for the DoQ authors[1]: after some discussions within IESG/IAB, I am afraid that UDP/853 won't be allocated to DoQ. Nothing definitive yet of course but IAB/IESG have raised the following concerns:
* Lack of real technical motivation (except for 'symmetry' or for operational reasons). * Moving DoDTLS to historic will not help, as it will simply return udp/853 to the pool to be re-used later. * The *currently* possible demux between QUIC & DTLS is not something carved in stone forever. Hence, a future problem can happen if DTLS v23 cannot be demuxed from QUIC v19. This would put a heavy constraint on the evolution of both QUIC & DTLS, i.e., ossifying both protocols. Not to mention that both QUIC & DTLS want to expose as little as possible to observers, making demux of future versions quite improbable... Personally, I do not think that it is critical to re-use udp/853 but happy to work with the authors and the WG to attempt to re-use it. Comments are welcome, as usual ;-) Regards, -éric [1] I already have exchanged some email messages with authors and chairs last week, but it is time to extend the discussion to the WG
