Comment (by pabline):

 > All of advanced callbacks, closures included, can currently be removed
 by API with access to original instance.

 This is key for me. If we made `add_action` return a reference to the
 callback that was passed in, then that could be made available for other
 developers to use to remove it.

 This doesn't solve the problem of existing code registering unremovable
 callbacks, but is that so much of a problem? If there are mechanisms in
 place to make it possible to remove hook and filter callbacks, then it is
 up to developers to follow guidelines (or rules) to use them.
