Frost-free sillcock in a 12″ insulated wall?

New house construction in Zone 5A/6A. I was planning on installing an 8 or 10″ frost-free sillcock in a 12″ insulated R40 basement wall. The water line would be inside the wall, about 3 inches back from the inside surface of the sheetrock. The basement is highly insulated from the outside but conditioned only by the fact it is not insulated from the conditioned 1st floor. Any concern that the water line could still freeze at the faucet?

I've seen them freeze in fairly mild weather. The metal body of the hose bibb gets cold enough along its length to freeze the water at the far end, helped by the cold air that blows into the business end. The longer the better, I suppose. Folks around here seem to use foam covers over them in the winter, which is something you might want to consider.
they make longer, so buy as far as you are willing to risk
also would make sense for it to extend enough so it connects to the water line on the inside so you can replace it and get to the connection if it leaks, or have an eyeball on it
