It's only nessecary at the point in time when you set the min_compat parameter, if you at that time have krbd mapped an image. Correct. You are forcing the set-require-min-compat-client setting, but as the feature bit that is causing this isn't actually required, "rbd map" and everything else continues to work as before.
