Anyone implementing a SMB/CIFS filesystem on top of FreeBSD (e.g. a vendor)
will need to come up with support for ADS.  Whether or not any "FreeBSD"
application has use for them is maybe beside the point -- vendors have a
use for support.  Though probably every vendor who wants them has already
coded their own variant.
