Any change in such things tends to cause problems, so it is better to leave them alone unless there is an important problem to be fixed. Theoretical arguments trying to show that "this behavior couldn't possibly be right for any caller" tend to be unreliable. Whatever functionp does, code will have come to depend on it.
