Auto manufacturers set them up that way, so,seals and gaskets don’t dry out.

Agree.
Plus the HVAC system is designed to protect itself in colder temperatures. Will switch off the compressor if the evaporator temperature drops below ~3C. So we don't need to intervene at all. We get the dehumidifying function to the lowest possible temperature possible in a car's HVAC system.
