I think having the FNAF NPC'S able to attack other NPC'S around it if they aren't able to reach you or can't see you a way of having a kind of 'Substitute' So mapmakers can have the full ability to have 'Bait' for the Animatronics to attack giving the players a small time to flee from them. It could also be used for fun. It won't be to overpowered giving a max of 4 seconds to flee as quickly as possible while the poor NPC meets their death.
