Thus it is now easier to built a nice, sturdy bumper!

Doesn't do anything for determining violations of the frame perimeter by bolts in the lower frame areas. What they're saying is that you can have bolts in the bumper zone, and they won't count as part of the frame perimeter (and presumably, won't count as a violation). What they aren't saying is whether or not this applies below (and above) the frame perimeter.
