I believe that we concur on the uses.
I'm not sure if you are saying the CA:TRUE is a requirement.
I do not want to mandate that.  CA:TRUE is, of course, acceptable.

I think that today's revised text supports all of your use cases.
If you find some fell out of bounds, then it's a mistake.

I believe that by number of Registrar's the self-signed private CA will be
the most common.   It is what I have suggested in
draft-richardson-anima-registrar-operations.
