During a game you often end with a bunch of small and tiny stations, such as a logistics bay with one solar panel. If they get damaged your options are to a) keep looking at a damaged component, b) put a repair module on every single station just in case or c) fly around and either delete and replace or put a repair module on it.
This doesn’t remove the need for repair modules, as they are still very much superior in response time and possibly repair time.
