Whatever comes out of the EDHOC discussion about transferring public keys by value could also serve this purpose. In [82] and [88], contenders for that seem to be stripped-down `COSE_Key`s, C509 "certificates" (AIU they're not necessarily certificates but can be RPKs just as well) and CWTs. This has some overlap with what can currently be expressed in DNS (public-by-value would relate to SubjectPublicKeyInfo).
