I haven't done any instructing recently, but when I did, I taught slow
flight, stall recognition and avoidance AND stall entry & recovery. I
don't think they have be be exclusive of one another.

Plus I think learning to recognize and avoid stalls is probably a
better risk-management strategy given that it can be easily learned
and mastered by pilots of all skill levels. In principle I agree that
ALL pilots should be fully competent at slow airspeeds and at
recovering from stalls, but I would also tend to say that there's a
lot more that we can teach pilots before we set them free to fly on
their own.
