I think it's a great gesture, and no doubt there will be some excitement from some players who will make use of these styles - Kytrinh seems pretty excited about them - but I just played a 5 hour gig in the lounge of an upscale Italian restaurant, and had the (small) dance floor full from 8 to 11pm, and I would not have been able to use any of those styles ... but that's just me ...
