and show recovery using rudder to prevent further roll & yaw, instead of aileron which involves risk of exacerbating the situation
Unless the OEM guidance differs, rudder should be used, sparingly and as required, to prevent further yaw. A bit of roll is not a concern and can be fixed up once the aircraft is back in unstalled flight. Suggest those who have a more cavalier attitude should read the relevant version of AC23-8 to get a feel for what might have applied to their aircraft in addition to whatever might be included in the POH/AFM
For any not-ancient certification, aileron should be quite effective right throughout the stall and, unless there be some words in the POH limitations proscribing the use of aileron, there is no reason why you can't do so. 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. The basic story is, read the POH/AFM guidance and limitations and stick with that information.
It's a case of horses for courses and, definitely, not one size fits all.
