In my opinion an instructor has no place teaching people to fly if they cannot effectively teach stall recovery involving a wing drop. If the aircraft being used aren't capable of performing such manoeuvres, then they are not suitable as a trainer.
As far as spin training for pilots not interested in aerobatics they must be taught, at the very least, to recognise the symptoms of an impending stall / spin. The most common phase of flight I observe as leading to an unintentional spin entry being the turn from upwind to crosswind and from base to final. If an aircraft enters a spin at that point it's all over, so the ability to recover from a spin is of no use. The incorrect use of rudder in climbing / descending turns I see is staggering. The classic is the turn into final during a glide approach - the fear of over banking leads to turning using rudder and holding off bank with aileron - and I see so many people either totally unaware they're doing it or don't see a problem with it. Getting into the right aircraft with a suitably experienced and qualified instructor at a safe height will soon cure pilots of this habit - it only takes one demonstration to get the message home. I also firmly believe spin entry should be taught in a climbing turn - some power, out of balance with aileron input to hold off bank. Too many pilots will recite spin recovery as "opposite rudder and stick forward". The first two vital actions in the event of an unintentional spin entry to effect recovery (in fact all spin recoveries) are throttle closed, ailerons neutral, then you can think about identifying the direction of rotation, applying appropriate rudder input, then unstalling the wings (might involve back stick if inverted spinning).
