Part of the problem is terminology. What should be specified is spin entry recognition and recovery, not incipient spin training.
The intent should be to recognize that the aircraft is starting to depart from just stalled to stalled and now yawing with the wing dropping which is the entry to the spin.
If immediate positive correct control inputs are applied to reduce AOA and prevent the yaw at the beginning it is impossible for the aircraft to spin. That is the lesson the PPL should be learning and it should be presented as a realistic scenario like a stall in a climbing turn trying to avoid an obstacle on a short field takeoff or as a late base to final turn with the nose ruddered around to try to get the aircraft to point at the runway.
Teaching PPL's how to enter a spin so they can recover from the spin they caused is IMO negative training
"Spin" training IMO has no place in PPL training it should be done as part of an introduction to aerobatics course.
