pam_succeed_if's pam_sm_setcred

[Ian Ward Comfort]

As of Linux-PAM 1.0.4, the pam_sm_setcred function of the  
pam_succeed_if module always returns PAM_IGNORE:

     PAM_EXTERN int
     pam_sm_setcred(pam_handle_t *pamh UNUSED, int flags UNUSED,
                    int argc UNUSED, const char **argv UNUSED)
     {
             return PAM_IGNORE;
     }

Is there any design reason not to give this function the same  
succeed_if behavior that the other pam_sm_* functions have?  I ask  
because I have a real-world scenario in which I'd like to use  
pam_succeed_if to skip setcred for some modules under certain  
circumstances.
