sure, i can understand that, and maybe i should temper my earlier remark.

how about "v3 public keys for which you do not have the secret part need
to die already"?

This would mean that v3 signatures couldn't be checked (except by people
who control the given key).  but no one should probably be relying on v3
signatures anyway, since they're all MD5-based.

That's more radical than what i wrote above, but i think i wouldn't mind
doing it.

People who really want to dig back through an old encrypted archive that
they haven't re-encrypted can always build from older source
specifically for their re-encryption stage.
