I don't think it will work on cameras like the D3 or D4 or ones with supplemental battery packs

Try changing a lens............
I fail to see how it would impede changing a lens. I change all of my lenses left handed while holding the camera with my right hand. Push the lens release button with the left pinky and rotate the lens and remove it. Same goes for attaching and indexing lenses on my F2's. I have been doing it that way for decades.
Perhaps you could elaborate.
Elaboration: Changing a lens. Not just removing it.
OK, removing and installing a lens is an easy, one-hand operation.
Now explain how you put on the front and rear caps (where did they come from?), place it in your bag, get another lens out, remove the front and rear caps (OK, where do they go now?)........... all with one hand.
My bad, I was not aware that when you got one of these that your right hand had to be surgically attached to it. I was running under the assumption that you could actually slip you hand out of it when you were not actually using it
