The use case is for constrained bootstrapping (BRSKI for 6tisch).
I would be happy to say a lot more, but essentially, I want RPK, and I want
certificates, and I want them together.

A way to "send" the certificate by reference, in a privacy preserving way is
sought.  Of course, this mechanism could be applied to other AKEs as well.
Using PHB's UDF https://datatracker.ietf.org/doc/draft-hallambaker-mesh-udf/
would work.
