You could quite easily wind up throwing restrict on something that does actually get aliased, which would result in some weird heisenbugs. That said it may be true that restrict will do better than the others have, but it's a lot 'newer' (even though it came from a 15 year old revision of C it seems like adoption of it has been particularly slow) so I'm not sure the jury's out yet.
