Kind of interestingly, the government actually does use that mosaic theory elsewhere, when dealing with 'national security information'. There is a concept that there are types of information which are unclassified individually, but which can 'become classified' if joined as part of a compilation. Of course the law is not exactly the same as information security but I don't see why the government should use mosaics in one area and then claim they can't be used for similar concepts elsewhere.
