My intuitive sense is that the IANA registry sometimes lags behind
RFCs/BCPs - e.g. the registry currently lists both NULL cipher suites and
(as one example) TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5 as DTLS-OK.
So my preference is to point to BCP195 (and agreed that "the BCP document"
-> "BCP195").
I could open a PR and would love you to review, if that works?

Acknowledge. Please let me know if I should change it.

I think Appendix F only gives a bird's-eye view of the changes, rather than
listing specific cipher suites. So specifying it under "requested IANA
actions" might be confusing?

Thanks for catching, fixed (on the github repo).

best,
