In addition, the more electrical components are allowed to move/shake, the more likely they are to disconnect. Added strain on wires and connectors can make a bad crimp fail or a spring-loaded connector release a wire.

If I were inspecting robots, I would not pass anyone who used only "fuzzy" Velcro to attach their electronics. If "industrial" Velcro was used, I would spot check the components and make sure that nothing was in danger of failure.
I've never done FRC inspecting but from my ftc inspecting experience you can not just fail someone for a poor design choice. For instance this weekend I had a team who used fuzzy Velcro to vertically mount their ZTE phone. Would I ever do this no... But I couldn't fail them for it. I did recommend zip ties for the day and for them to build a more permanent solution. After I found out they had a 3d printer I pointed them towards some files I found on grab cad. But, those were only suggestions if their phone falls off mid match and gets destroyed it was their fault.
