I'd add a third camp who thinks that people who can't keep the
passwords straight shouldn't use it at all...  Or that someone
else should very carefully set up passwordless access to the things
they are allowed to do.

It would take a change to sudo to make it check passwords for
two different users and permit the access either way.  Probably
not a big change since it already knows how to do each separately.
