We had the FDIC here in Feb/ March. They asked if we did QMs, and they asked me to prove our status as small/rural. All in the pre-exam packet. That was all. They didn't ask anything else. That being said, that doesn't mean that a different exam team or a lawyer, or an investor, even an industry survey later won't ask you to what kind you made.
I think you did a great thing! Changing systems or processes is HARD, so I salute your effort!
