EDIT: Also leaving the a/c on and not turning it off and letting air circulate through it could lead to a smell developing in the ducts too.

No I don't want the ac on upon start up. I want it to go back to recirculate upon start up. I always power down my hvac usually 30 secs or so before shutting the car off. The problem is on startup 9 out 10 soon as you start driving if you forget to press recirculate it fogs up the windshield from the heat. So then you press recirculate to kill incoming air and all is well. Literally every car I've ever had (going on 20 something cars) will allow recirculate to be on during start up with the ac off.
