Is it possible for the courts to use this system to search a defendant's phone for leaked documents say? Like if NSA learns that one of a small group leaked document X, can they get a court to force Apple to add the hash of Document X to the database on that group of people's phones? If so, I bet this becomes the new norm for investigating leaks.
