It only matters, what is the marginal cost to the door vendor. Their profit margin is razor thin. They make those doors by the millions and sell them as a commodity. So yes even a few cents is too much.

We proposed putting a fuzzy-logic controller into a Maytag washer. Maytag said, any controls had to come in under 75 cents including sensors and actuators, for them to make it up in pricing. We couldn't manage that back then (the processor chip was several dollars) so no deal. Because washers are a commodity from the manufacturer viewpoint.
