Did you have a reason in mind for why this would be helpful?

I think nothing in this spec prevents the use of an alternative discovery

I modeled the design on the IPSECKEY RR, because it's a somewhat
similar discovery usage, and I think I just used the same thing they did.
I didn't go through a very extensive search for the best name.
