Lets all not forget that the most sound structure on the perimeter is the bumper themselves. Adding an additional thin sheet as the backing is bonus.
I have yet to see a bumper break completely in half due to impact.
If it happened, I bet rarely.
Mandatory bumpers (in how they should be made and mounted) in itself should be self-sufficient. If not, why make them required (considering the purpose is to protect robots)?
If the new rule implies that the bumper themselves may not hold up during a competition, then the rules for how to make them should be modified to meet its objectives in any situation.
