It's more program philosophy than a social issue.  When you
disagree with the author about what the program is supposed
to do, the source code is the place to start.

Pam can check a password against any number of things you
want, but I don't think there is a way to tell it that
other user names are OK in the same run.  You might build
an appropriate permutation of the password file for a
service (where the expected user name is matched with the
alternate acceptable password) and add that to the list that
pam should check.
