One could argue that if you are taught spin avoidance and fly the aircraft on the correct side of the envelope you will never need to see a spin as a result.
When I learnt to fly we had to demonstrate spinning and I had to spin for my Instructors course. I see no benefit in teaching spinning at basic level that is better than spin awareness.
If people want to learn to spin then they should do it post PPL with guys who are experts in the field at places like Ultimate High who do an amazing upset recovery course.
