This sounds like a reasonable request, though i personally don't like
key IDs in general [0].  What would you think about the full fingerprint
of the subkey?  is that too long?  at least it would be unspoofable.

If we're going for something that can be spoofed/confused, what about
the date of the subkey or something else that's more human-readable?
