FWIW, this is something we'd like to do in Chrome OS. Dealing with fs-attrs has traditionally been a pain, so this kind of simple passing down of privilege would be much nicer. It means we'd have a programmatic way to decide what privs a helper has, rather than having to represent it in some way on-disk.
