I suggest that the OWT about aileron's being a killer in the stall dates back aeons to the rather early rag bag aeroplanes with yaw and local stall problems associated with the use of aileron.
Agree. The DH 82 Tiger Moth is a good example. So was the Wirraway. The DC3 too especially a full flap partial power stall. The myth of rigidly avoiding any use of aileron to level the wings following a severe wing drop in any aircraft, has been perpetuated throughout the ages. Occasionally faulty rigging of a wing may cause a sudden wing drop at point of stall. If that occurs the aircraft is unairworthy and the maintenance release so annotated so the next pilot to fly that aircraft is not caught out
