It can, but it isn't largely because the classical solutions solve the problem better and you usually have to resort to classical solutions to solve MITM anyways afaik. However my point is less about practicality and more QKD seems more like a physics or engineering thing and not a computer science thing.
After all, this is supposed to be a computer science prize not a make money prize, so which is more sellable should be besides the point.
