Adding new ciphers would still involve patching existing 1.2 code, so I would expect the same answer: move to DTLS 1.3 when its ready

Do you still think it would be a good idea for us to propose a draft on the same? Thanks!

For a number of cipher suites, this would allow to reduce the per-record overhead in (D)TLS by 8 bytes. Is there any interest in breathing new life into that draft? In our scenario (DTLS for a legacy industrial wireless communication system) every single byte counts. That is why we would strongly support reviving this draft...
