It gets back to descending styles. If you only touch brakes once for the entry of each turn, you don't have a heating issue even on steep terrain. If you want to control speed, and are putting them repeatedly on the straights, then yes rim brakes are an issue.
We did Everest challenge with 10 mile descents and 17 percent grades and never had a problem with calipers. Of cours we were also doing 65mph
