Comment (by kwisatz):

 '''Appendix:'''
 I am no longer 100% sure about this.
 The problem is, what happens when the plugin hooking into the
 authentication process is unable to perform authentication (perhaps the
 authentication server is unreachable). In such a case, you might also want
 to return a WP_Error, but in this case, it's not that the user is invalid,
 it's just that we cannot tell.
