The high flange hubs were designed to shorten the spoke to rim length to take the additional effective weight loading caused by g-forces on a banking back when people were using box section rims. When you start going to taller rims, especially once you start hitting 80-90mm they really aren't necessary if you have a good build, which would include a hub with an adequate axle.
I ran a road HED S9 front with a screw type skewer when we set the Nats 45+ TP record at Carson and a bunch of other races. Thought it was stiffer than the high flange box wheel I use in training.
Why anyone wouldn't run a disc rear in all events, I dunno.
