They don't care what it is on, but if you send it to them what you get back will most likely come back updated. The problem with updating is mismatched. If they update one thing and say your controller is on a different update (old) then things can go screwy. So IF possible keep things in same time frame. Don't update part if it is a all around update, to include batteries.
I think like this for the "accident" ... "Before we begin, is your firmware up to date?"
Or backed over your packed FM bag with your car. That's sort of pilot error, just not UAV pilot error.
