FWIW, I believe that It Has Always Been Thus.  The man page for 
getgrnam() and friends specifically sez (at least on Mac OS X/Darwin) 
that the routines deal with /etc/group.  Poking around in the ashes of 
the long ago, I believe that even back to version 5, it was assumed 
that /etc/passwd was "in sync" with /etc/group (i.e., passwd listed a 
single group id, and /etc/group listed the group id's, together with 
each id's list of users [as names]).
