I certainly could have done with a dropper post today. 4000 m of steep descents with some 25% ramps. I’m not that fussed about the aero, but a dropper would have made these descents so much more comfortable. I wouldn’t be surprised to see them on endurance road bikes in the near future. Even on the flat I prefer my saddle a little lower than climbing, especially when fatigue sets in on a long ride.
