Actually is not just Ford who have this system, other brands have the same vacuum system too, my pontiac does. The reason is because in the event you have any vacuum related problems during extreme weather you might be freezing inside the car but, at least, you can still drive with a good visibility with the defrost option. Even with electric actuators there are still problems, you can search for Blend Door Actuator (which is part of the HVAC system in cars and controls air temperature) and see it is a common problem too.
