In the Lambek Calculus which I used in my dissertation there are left and right slashes that do *not* mean division. Their corresponding 'multiplication' has a black bullet notation (probably meant originally as a bold multiplication point), and therefore using a mathvariant=bold of the slashes would have made excellent sense in that notation (indeed, as I said, I actually went and tried to do that by wrapping a \mathbf around the slashes, but that didn't appear to work, so I just gave up on that idea). Since the meaning of those slashes is different from regular division and set-difference, say, the mathvariant solution would have been quite appropriate by your standard as it was meant to underscore a deeper semantic distinction. This is just meant to help clarify the situation a bit better, but in no way as an attempt to solve the actual question itself, which I gladly leave to the experts. -- Andreas
