These drafts seem quite low value to publish:

The existing OCB document [RFC 7253] is cited by exactly zero RFCs (
https://datatracker.ietf.org/doc/rfc7253/referencedby/), so having a
specification for ciphers with block size != 128 seems of particularly low
value.

The existing RC5 document [RFC 2040] has 6 RFC-level citations, but as far
as I know, RC5 has practically no usage in IETF protocols. AFAICT, RC6
isn't even specified in an RFC. Thus, test vectors for these algorithms
don't seem that interesting.
