Looking at the 'X' lens, it appears that Leica could easily have put the DOF scale there just like their other lenses. So, it appears that they did not do so for marketing purposes only, which would obviously be a bad, bad decision. Good luck on getting a statement from Leica.
More than likely the movement of the ring and the distance it sets on the lens (remember, focus by wire) is not linear, and thus a static engraved scale would not have been accurate at all distances.
