The spots are only patched in Infected. Since you can just throw a semtex or shoot a rocket in those places, there's no point. I understand patching infected, but adding throwing knifes while the spots are patched is stupid... It's already bad enough they can just throw a knife at you, now you can't even hide. If they're going to remove glitches then remove throwing knifes. It make infected less fun and end to quick. Probably the only plus side to throwing knifes is that it makes it harder for people to MOAB boost with their buddies or split-screen controllers.
