That wasn't a mistake, but an engineering necessity. As it is Leica still has rear element clearance issues with the M8, due to some lenses being designed to nearly brush the shutter on film models (The shutter on the M8 is placed slightly forward of the normal location in order to give room for the sensor AA/IR filter). These same lenses of course aren't compatible with an M5 or CL due to the swinging metering arm hitting the lens.
