It lowers the rate of growth (and thus the keyserver load) since gpg
would not send out expired sigs to keyservers. The GD itself doesn't
export keys, so if we can prevent users from doing it accidentally,
then the useless sigs never get onto the keyserver net.

That's up to the keyserver authors. I'm not against it, but they
might be as it involves special-casing certain keys.

I'm still holding out hope that the current 14 day expiry is because
the keyserver is still in beta. The GD is supposed to revalidate keys
every 6 months, so a 6 month expiry seems obvious to me.

I wonder if it is better to "clean" the keyring by simply not showing
or preventing the import of sigs that are not useful rather than by
deleting them after they are already imported. Flags for "don't
show/expire/import expired sigs" you can set once in gpg.conf and
you're done. Deleting expired sigs you have to do every single time
you do a --refresh-keys.
