Perhaps the while light would ruin the IR layer.

By its nature a light diffuser would reduce the sharpness of the display. Resistive touch screens in my experience don't have much if any affect here. They just reduce the total brightness.
Also it might have made the device too thick. Since it would have the diffuser and then a raised bezel above that to house the IR sensors.
