Ray:
I see your point. It also appears that send-n and unused would never by themselves raise response size issues since I wouldn't expect to see a send-n RR in or an unused RR for a domain name that would have other NAPTR records in its RR set. So let me bump the naïve question up a level:

Please sirs, may we have an e2md WG that will analyze proposed use cases guided by RFC 5507 & RFC 5395 and propose appropriate implementations?

It might, but it then doesn't meet some of the technical requirements for
some of the use cases.

For 'Send-N' and 'unused', in particular, NAPTR fits because these answers
are given back instead of "communication end points" in response to the
usual DDDS algorithm query.

A new RR type for those would be self-defeating.
