But then:

6. Guidance in the use of these Imperatives

   Imperatives of the type defined in this memo must be used with care
   and sparingly.  In particular, they MUST only be used where it is
   actually required for interoperation or to limit behavior which has
   potential for causing harm (e.g., limiting retransmisssions)  For
   example, they must not be used to try to impose a particular method
   on implementors where the method is not required for
   interoperability.

To me this indicates that we should keep them out of registrations procedures.

(I also note that the "MUST" in the text I quoted shouldn't been used if the text followed its own advice :-).
