My answer would be "no" but I also beleive that for some riders, myself included, it's easier and safer to learn on a SS. I started on a Zuk SV650, and found that the lower powerband actually made the bike handle less predictably. This led to a few low speed cornering scares, many of which I feel could have been avoided with smoother throttle response.
I do think this category is quite small, and therefore a blanket "no" should suffice.
If there was a way to govern a supersport to say <6k RPMs, then imo you'd have one of the perfect beginner bikes.
