My theory is that to allow the AF motor to work while minimizing power and size requirements, the focus mechanism of the lens needs to be easily moved. Much more easily than a typical MF lens. When you manually focus an AF lens you get a real sloppy feel to the focus. This also means the lens focus will change at the slightest bump. The motor to move an appropriately stiff (but very smooth) Leica lens mechanism would be to big to be practical.
