Pretending to be Elad's keyboard: 

Attached diff let's call kauth_register_scope() with a NULL default
listener. from tn2127:

"callback is the address of the listener callback function for this
scope; this becomes the scope's default listener. This parameter may be
NULL, in which case a callback that always returns KAUTH_RESULT_DEFER is
assumed."
