Which has everything to do with the frame and absolutely nothing to do with the dropouts.

The only possible functional advantage of forged over stamped is the thicker forged could possibly assist in axle alignment.

While one could make an argument about having the "best" part for the "best" bike, why isn't that true for track bikes? I don't know of a stamped Campagnolo road dropout but they certainly made stamped ones for track ends. I can't imagine a place where strength more is needed than in a sprint.
