On the day, the stall that tries to kill you will not be some genteel church tea party thing, with perfect manners and plenty of notice. It'll probably be at low altitude, in marginal weather while you are craning over your shoulder looking for the threshold. You'll be out of balance, at low power and missing all the cues. And that's when you'll be glad you understood that correcting a wing drop and recovering needs to be instinctive, whichever way the aircraft takes you. If you can't do that, it's probably not the aircraft that's "un-airworthy" but the pilot.
