There is no reason for the short name to be visable _except_ when there are interactions with DOS, this comes down to dosemu, samba and backups.

I think this would work out to be just the same as using a directory by directory sfn_backup, and IMO it's better to do it in userspace and keep those horrors from the kernel.
