Yes, this would be my view on it, and built into the DTP or QRB the same experience build up that is in the current quals, so you do the SD sylabus then have to gain experience to use the full qual, so depth progression and tech progression.
Managing a stage bottle and reg is not too difficult, no where near as difficult as managing buoyency correctly in many cases.
To me if you are doing a deco dive it should be done on Nitrox as air is Cr*p for deco, so in the same vain if you are qual to do deco do it on the right gas.
Just my view, don't think they will be that bold, but you never know.
Dive Safe, dive Nitrox
