CmpQueryKeyName endless loop

Created an attachment (id=2919)
dont enter while just return STATUS_NOT_IMPLEMENTED

Believe Function CmpQueryKeyName in ntoskrnl/config/cmsysini.c
puts thread in endless loop with the following code

while (TRUE);

Not sure if this was done for a reason. Does it still need to be there?
Any reason it doesnt just return STATUS_NOT_IMPLEMENTED?
