Depends. Could work if you also have an emergency stop button in case there's something (your car, pet, etc) under the door while closing it, operating remotely deprives you from the ability to keep the pet away or even see the danger. Then, you'd need some IR/camera sensors and a 2nd actuator to stop the door automatically when a sensor is triggered. With that said, you're on the right path, either automation under the full control of the user or no automation at all. I'd even say, the current plastic gearboxes used in motorized garage doors aren't worth the trouble either, just have a good spring and do it manually.
