Thanks for being here at ScubaBoard where you can at least listen to comments, whether or not your company agrees with them.
My take on it:
Most divers dive rental gear, and most divers who need rescuing for not having positive buoyancy are in rental gear. Even those divers who own their own BCD/regs will use rental weight when traveling. Rental gear (especially weight) is nearly exclusively weight belts. Having two right hand releases means that when it matters, the wrong thing might be released unless the rescuer happens to notice that it is a newer Dive Rite Transpac, and looks for the double right hand release setup. The Transpacs from twelve years ago were certainly not right hand release, or I would have noted sent a note of complaint when I bought mine then. Nor were any of ScubaPro's several attempts to copy the Transpac. I teach in a Transpac, and one of the things I brag on the Transpac about is that from bare skin tropical diving to tech diving a single BC can do it. Modeling good behavior is a basic part of teaching, and having the buckle for a BCD setup for a right hand release is simply not good modeling.
Especially for a company that markets a BCD that goes from Open Water to sidemount cave diving, it seems strange to think that there is one set of standards for 'PADI training' and another for 'real diving'. By that logic, your BCD either does not belong on PADI divers, or it does not belong on cave divers, since there are different standards for each.
Moreover, the right hand release is simply not a 'PADI' thing, it is a basic diving safety standard, and it's taught in pretty much every course from open water to rescue to instructor, regardless of agency. (NAUI, PADI, IANTD, SDI, TDI are the ones I know.)
I know you are a tech gear focused company, but thinking of the right hand release as a 'PADI thing' to be dismissed for convenience's sake is somewhat irresponsible, in my humble, personal, (and likely wrong) opinion. Regardless of the dominance of weight integration, training still place in borrowed/rental gear, and that means weight belts. If people want to buy their gear and move the buckle to the other side, that's their business. But as a manufacturer, especially a manufacturer who is posting informative videos to new divers, it seems like you have to be aware of modeling behavior.
