    If it just modifies /behaviour/ it can't really do much. And what can be
    done here is more the job of the scheduler, not of the filesystem. Keep your
    hands off it!

    If it somehow modifies /on disk format/, it (by *definition*) isn't
    compatible. Ditto.

    Without those, it is next to useless anyway.
