I look at it as just a very compact way of organizing a test screw collection. I have these...

as well, purchased earlier, but they must be taken off that infernal cable and mounted to a board to make them useful and, when that is done, the result is way bigger and heavier than the little plastic thread gauge.
I actually have those! But they're called "Thread detectives." They were $17 a piece.

I was thinking about your solution using that board...and while it would really be helpful when you're working on a car or other machinery and need to remove the nut/bolt, I still would rather use the board I made if I was sitting in front of a large bucket of nuts and bolts. Having to thread each of those nuts off to check for bolts or bolts to check for nuts would be annoying.

Again, I think yours has its place, but I'm always sorting through nuts and bolts. I mean, literally always. At least...that's the way it feels. Being able to grab a bolt and thread a nut real quick helps to sort my confounded nature quickly.
