It's weird Mike hasn't replied yet, but I vaguely remember him saying that he wanted to prevent fragmentation of the package.
That being said, the terms of the license don't prohibit you from posting code that modifies the package (going back to a question in Bruno's original post). Nor does it prohibit a wrapper package. -Andy -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
