I'm happy to call it "registration" too. I think this should tend
to get us thinking about the right thing. How should the intent to
receive email for a domain be signaled?
The current model permits no email-specific registration, in order to operate a
mail-receiving service. Anything that eliminates use of an A/AAAA record
changes this basic flexibility.
So the requirement "How should the intent to
> receive email for a domain be signaled?" is, in fact, a very basic change to
the core Internet mail service model.
In a clean-slate exercise, there are good reasons to consider imposing that
requirement. In a world with decades of momentum for administering and
operating email a certain way, changing the registration model warrants
separate, careful, and extended consideration.
It is a topic thoroughly worthy of that consideration.
However, trying to squeeze that effort into the RFC2821bis process is a good way
to kill both.
