If I am correct, there is a "vent" hole in there to help prevent it from getting vapor lock or 'burping' when you put fuel in the car. Of course, I could be way off base - just the first thing that came to my mind. When I put gasoline into my 2017 Stingray, the pump often "shuts off" long before I have filled the tank. I have to remove the nozzle and put it back in about 2/3 of the way in order to be able to continue fueling the car. For some reason, this happens a lot at Costco and one of our local Shell stations.
Maybe it is the flow rate of their pumps or perhaps the design of their particular nozzle. No idea.
I just miss the good old days when the gas tank filler was under the rear license plate (more easily accessed from either side) and the filler hole was big enough to put the nozzle in with room for air.

My 2014 does not have a gas cap. I would agree that the hole may be some sorting a vent.

As suggested before, it probably was there for a gas cap tether before they made the decision to go capless. Sometimes designs go in different directions as they develop the car. The hinge design was probably already approved for production and not worth redesigning for the final configuration.

Is this part shared with another GM vehicle that has a cap? It might be a common mold. Or it could be something that allows the piece to be installed easier / faster, IE: an alignment jig or tool goes there during assembly.
