I think it's excellent that someone has had the balls to consider that a turn-back is a sensible manoeuvre for a high performance aircraft. The moment you achieve a climb rate in excess of your glide angle this procedure becomes sensible. All you have to to is ensure you have enough sky underneath you to do a 180. The rest is in training. Not to do so risks wasting a valuable airframe. It's about time thinking was introduced to aviation.
