Uhhh my 96 civic had an air conditioner button, and it also turned on when you turned the defroster on.
You’re making shit up, it’s a simple interconnection, and the physics of air conditioning removing moisture has been known for a long time.
During winter snow constantly gets inside of a vehicle, so without an interconnected ac with defrost, the interior would always fog up. It just may not light up the button, but defrost turns the ac on.
