wondering why..question on bumper plugs

Our new TT has the standard hollow rear bumper for sewer hose or other storage. I know some do not use the bumper for sewer hoses due to rust problems.

Question is: The rubber plugs on our new TT bumper have a 1" square hole in the center. My question is why would they do that? Seems the hole would let water in and contribute to rusting, or are they smart and the hole is for ventilation to prevent rusting. Just wondering...

Ideas?
