Forward compatibility (at least the way we're doing it) isn't
particularly stable anyway.  I would not be surprised if it's easy to
crash blender that way.  Besides, 2.5 is such a major change, that
maintaining forward compatibility would be far too much effort to be
worth it, anyway.  You can't avoid making changes like this forever.
