You make an interesting point.
I've certainly been through a couple of very interesting biennials in the states, where we investigated the low flight end of the envelope, in different configurations and attitudes and it was fascinating learning.
On the practical side one might reflect that many pilots pootling around SE UK at 2000 ft or so would have plenty of altitude to execute a stall recovery, but precious little to recovery from a spin. In the circuit, a stall recovery is certainly possible, a spin recovery unlikely (although I believe not unknown.)
So whilst I am certainly not anti spin training, I do believe that be familiar with slow flight on type and pre stall symptoms is very important.
