My point was that if we have a better system, we could migrate blkid and other users to new interface, and maybe in a few years, we can deprecate that interface. So we do have to maintain them for at least the medium term, but that shouldn't stop us from divising a better interface, and then gradually migrating systems to use that newer and better interface. - Ted
