We could proceed by consensus: the PEP author publicly proposes a PEP delegate, and if no core developer opposes, that person is officially accepted as delegate.
I think this is too decentralized. I think there should be enthusiasm for the delegate, say two "seconds" (with discussion of why they think the delegate is appropriate) besides the PEP proponent(s).
Often PEP authors have a pretty good idea of who can be a delegate for a PEP. This is especially true on specialized topics which only a couple core devs are interested in discussing actively.
I agree that this is an important point. I think you (disclaimer: I'm a social scientist, but not a committer) should be careful that delegates be broadly respected, and where possible have interests in other areas of Python development besides the one they're delegate for.
