Their goal was that any features added that were specific to afs, cifs, etc should not add overhead to systems that did not have that filesystem type. I can't speak to how well they succeeded, but that was their goal.

Bear in mind that I got similarly broken results from Solaris 9 and 
OSX/BSD verion of 'find' when scanning the top levels of the cell, so it 
isn't unique to GNU.  The OSX find might include GNU code - it has a lot 
of similar options beyond traditional Unix find.  A quick test showed 
Solaris behaving itself today but OSX still giving the same errors.
