I'm not sure about punitive rough as a design element, maybe more of a maintenance element, or rather a photography element.
Thanks to social media and camera phones etc there are more and more photos and videos of courses available to view and photos appear more attractive with contrasts. And sand and water and grass, different colours and lengths of grass, mowing lines and patterns etc all provide nice visual contrasts, especially if taken in sunny weather.
Perhaps we have reached a maintenance by nice views in photographs phase in the game?
