If it is stupid and it works, then it ain’t stupid.
Looks good. If you got a lot of cast iron pans, I could see it ripping the screws out that hold the hooks. If that ever happens, make the hole a little bigger and stick a bolt, nut, and washer so it holds better.
Every once in a while the rod may shift. I would wrap a rubber band so that it is “held” to the hooks just enough so you could tell if it shifts.
Dust sources are:
You could consistently clean the air with a hepa filter that you clean regularly.
You could install a hrv system with a hepa filter on the intake duct while being anal about no leaks in the ducts. Then set it to make positive internal air pressure.
You could get a vaccume and mop roomba robot.
You could take off your shoes before coming into the house.
You could try to seal all your existing ducts.
Between all these suggestions, I think your dust would become negligible.
Fun.
