NSS can express at least the part of "look into passwd and continue if
no match was found". It would be easy to have a NIS config file to
express "look for / accept the following users/groups/patterns". As
such, I don't see the need for keeping it in /etc/passwd. In fact,
having such a filter functionality would likely be useful for a number
of data sources. It could certainly make the code much clearer by
prodiving composition of independent modules.
