And it would be even more nice in the case of doing e.g. backups, even if it's from local fs to another local fs.... so that one doesn't have to do another round of diff'ing, because one already knows the copy is guaranteed to be valid (or at least the checksum is from the source, and a further scrub on the copy would reveal any silent block corruption).
