I also think that this should exist as an option.
Back in the days of IKEv1, there were things that we left out of registries
because we were told that secret agengies would be doing implementations, and
they didn't like to be in a list.  This might well apply here as well.
I'm okay with that situation, and I agree that a PEN/OID is a good way to do that.
