Great diagram and reasoning, however I'd like to add that I've encountered a couple lenses where at certain focal lengths one corner is softer than the other 3 tested perpendicular to a flat surface, perhaps due to field curvature the opposing corner is still within the DOF of the lenses settings and scene while the bad corner is further out. anyhow neither lens was bad enough to worry about in everyday situations.
