I've owned, the 10D, 20D, K5 and K3 and the respective battery grips. Never saw this until I bought the fullframe.
Well it's not the body as it'll sit flat on a level surface; just the grip where it meets the body isn't flush. The bottom of the grip which I have a Manfrotto 488RC QD plate attached to is flat.
I wonder if it's done on purpose to provide tension to the locking screw so as not to back out accidentally. The tighter you go, it seems the grip's top plate flexes to match.
