I would love to see tamperproof panel screws.
When I was doing residential work I constantly had problems with guys getting into panels. I bought a couple dozen #10 Tri-wing machine screws. I got mine from a company called Small Parts Inc., but I think Grainger sells them, too.
I would use them in place of all the panel screws, and leave the original screws in the bottom of the can. When we'd completed trim-out, I'd just put the original screws back in and take the tamper-resistant screws onto the next job.
Worked like a champ, I never had anyone get into the panels after I started doing that. But it's also a double-edged sword! The one time I forgot my tamper-bit set even working on the screws with vise-grips, I couldn't get the darn things out. I didn't know whether to be angry or happy that it worked so well.
