Interesting point. The footing in the hunter rings at Upperville is old fashioned sand, not one of the newer high tech synthetic footings. I do wonder if they would have looked better at a different venue.
However, when I had students showing on older packers, we selected show venues based on footing. There were places I wouldn’t take a wonderful older horse who objected to jumping on hard footing. Has decision making like that gone by the wayside too?
