Except this doesn't help you visualize it either. I can understand this argument for online boards that, when you click on a piece, highlight all the legal moves. This set doesn't do that, it basically just reminds you how the pieces move.

I don't think anyone that actually plays or teaches chess thinks this is a good set design. Honestly amazed by how many people called this clever. I also find it weird that OP claims it makes the board "easier to probe", when it does the exact opposite. This is a textbook example of making up a problem, rather than a solution.
