It also gives the longest lever for bending the frame there. Whether this design is good or not is debatable in my opinion. I don't like it.
I kind of like the Jesse bag mounts - they are flat mild steel attaching to the frame in multiple points. Strong enough to carry the bags, soft enough to just bend away when hit. And it's steel - you can have it fixed in the boonies.
