If the spin recovery in the POH reliably recovers, then it might be argued that it is a useful spin demonstration/recovery tool, since it emphasises the need to be familiar with the POH.
I seem to recall a pub discussion with GtE when I referred to 'standard spin recovery' and he (and I agree in principle) told me that there was no such thing, the correct recovery was the one in the POH for the aircraft in question.
On the other hand, I agree that for training purposes, behaviour similar to most types is preferable.
