The -17 and -18 versions clearly states that it can be used with DTLS 1.3. The GitHub version, which I assume will be the basis for the RFC also explains the psk identity differences between 1.2 and 1.3, which is great. I don’t think there is a need to do anything more.
Regarding DTLS 1.3 support, I don’t think there is any need for a -bis version, DTLS 1.3 is to my understanding already supported by the current document thanks to IESG.

Since you made this comment on an approved document (which the IESG no longer gets to “send back”), I’m not sure I understand what you are trying to say, but I don’t agree with any of the possible interpretations. > A lot of SDOs and industries are working hard on updating all (D)TLS > applications to work also with 1.3.

This apparently will take some more time: https://protect2.fireeye.com/v1/url?k=8ed7d76d-d14cee6d-8ed797f6-86fc6812c361-b378f81d3777bcda&q=1&e=5985dba9-7ace-4fe4-9ace-256b8615b396&u=https%3A%2F%2Fwww.rfc-editor.org%2Fauth48%2FC321 2021-10-18: Received email from Eric Rescorla that an open technical issue is ongoing. However, we should already have been working on a -bis for the DTLS profile that also supports DTLS 1.3; I can certainly agree with that. Grüße, Carsten
