By adjusting in the lens, it would work on any body you connect it to, including those which do not offer body adjustment. Also the body based corrections are currently still quite limited. On the latest Canons you can set different adjustments for each end of the zoom range, but that's it. The Sigma dock seems to allow you to set 4 focal lengths at 4 focus distances, which is much more comprehensive although finding 16 correction values doesn't sound like fun to me.
