    To-mate-o toe-maht-o.

    There really doesn't seem to be any real reason to create a new
    flag just because the granularity is different. The choice between
    _USER and _TYPE (and _ROLE for that matter) is arbitrary from a
    functional point of view. I say that since Smack has users, but
    not types or roles, _USER makes the most sense.

    Somehow I doubt that will be their biggest concern.
