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.
