I agree with Big Pistons, that there is no reason for a pilot to blunder into a spin during general aviation flying. That said, I believe that spin training has merit, in that it makes the new pilot aware of what the most demanding unusual attitude recovery would be. If you are comfortable recovering a spin, you can feel confident. I used to be surprised how many pilots I fly with have never spun. Now I realize it's just not trained any more.
The testing I do includes the requirement to spin many aircraft. Though I agree that is well out of the norm, it is still a good exercise, and I'm glad for my early training in spins, and practice all the years along the way.
I do believe that once you start instructing, or even checking out other pilots, spin recovery proficiency is vital. Similarly, commercial flying of a patrolling, photography, or unusual attitude nature should be flown by spin trained pilots.
I think it is a loss, that the desire to streamline flight training, is causing the removal of some subjects - including spinning. I hope instructors take the opportunities available, to familiarize their students with spins anyway.
If you can - spin....
