As long as staging isn't blind (i.e. won't stage off everything from a vessel when there are no more engines) then it should be safe to have staging allowed for every mission.
It is frustrating when your launcher has a bit of delta-v left-over and this blocks the departure node from being burnt because it would need to stage during the burn.
