what definition? what if admin has /export/something and /export/home on
different filesystems (same disk), /export/something starts nearing
capacity, and he has plenty of room in /export/home to give to it?

I suppose a feature with a limitation is better than no feature.  I
think XFS is pretty heavily used for things like /export and such a
feature wouldn't be very useful with changing inode numbers, but you're
right that it would still be useful for some applications.
