Idk, I can get behind some of it as a mechanical exercise. When I was a young'n and honestly thought I was gonna be an english lit major one of my teachers made me go a whole year without using any prepositional phrases. Did that instantly improve all of my writing? No, in fact everything I turned out under that rule was clunky and overedited. But after that year any time I ran into a prepositional phrase that I didn't like I had the experience to know how to rewrite it effectively. The point is training, not product refinement. Find a device you lean on too much, eliminate it entirely for a while, and emerge from the other side of this process with a better understanding of the crutch, knowledge of several ways to work around it and wisdom to know when to do that. It's not a substitute for taste, it's a tool for developing taste and the ability to refine things to your taste.
