 remove_filter/remove_action $callback type can be string/array too, not
 just callable, which is why it makes sense to make it more inclusive.

 (e.g. if theme/plugin has code to remove_action for a function/action that
 might not exist, it would make no sense if we would have to check if it's
 callable before calling remove_action on it, since this logic is already
 there in remove_action)
