[DNSOP] RFC6781 Cooperating DNS provider signed zone migration

[Viktor Dukhovni <[e-mail]>]

Is anyone aware of better descriptions of cooperating DNS operator DNS
provider migrations than are found in RFC 6781 section 4.3.5.1

    https://datatracker.ietf.org/doc/html/rfc6781#section-4.3.5.1

and Appendix D:

    https://datatracker.ietf.org/doc/html/rfc6781#appendix-D

Both descriptions could use more detailed prose (especially appendix D
that has none), and there are some mistakes in the diagrams.

Also which of the two processes do actual hosting operators support?
(To my mind, Appendix D is the more realistic model, but it is much more
sketchy than 4.3.5.1).

Would it make sense to write a BCP that updates 6781 in light of
operational best practices in the last decade?
