As someone who has played a lot of chess I don't find this useful. I'm surprised how many people have positive responses to this.
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.
