To me a local sig is basically saying, "I'm signing this key as a
convenience, but I haven't done proper verification, so I'm not going to
publicly vouch for this key." In that case, the only local sigs I can
trust are the ones that I myself created. And if I have the public key
that's a pretty good indication that the local signature came from me.
