    That's pretty insignificant on a planetary scale, earth loses atmo at TEN TIMES that rate πŸ˜„

    A civilization that can add enough gases to Mars to create close to Earth's atmosphere isn't concerned with minor maintenance like that. A small comet body's worth every hundred years (if even that often), child's play.
