Just re-read your post. It's certainly not just a skid plate. It's clearly a structural element. Hence the name, reinforcement plate. This is what the rear susension looks like when it's off. The back side of the suspension bracket is just hanging in the air, nothing supports it against flexing toward the middle (apart from the sway bar which is obviously not for this job).
