I like the hoe pattern you used. I have often thought of sealing a section of my MFT top off to give me a place to work when disassembling and re assembling anything with very small parts or screws. With entire top full of holes, i have to reach for a tray or some other way to work so those small items don't find their way to floor or drawers. With my shaky hands, i find it especially difficult to hang onto tiny screws. Your design would make it a lot simpler project.
