You do know that this is extraordinarily uncommon in modern sidemount and generally unnecessary right?
I don't know that, I never took an official survey. I am sure that it is not mandatory or a must have since most second stages in the market aren't "ambidextrous" (?). I have, however, talked with several long time SM divers and instructors and they love this feature.
