  Because it has to emulate unix perms by relating uid/gid to windows RIDs, which are owned, allocated and controlled by the system, and not under the arbitrary choice of the user, so the semantics wouldn't be the same even if we did create ACLs with unrecognised SIDs on them.

Can't think of a witty .sigline today....
