I think maintenance can be good. Obviously, people are in this because they feel the need for spankings. If the spankee goes a long time between them, it may cause them to feel the need to act out in order to get one. Also, maybe someone hasn't behaved badly enough to receive a disciplinary spanking, but they may just be slipping a little and maintenance is a way to reign them back in so to speak, before the behavior gets worse. When a mentor spanks their mentee, it can be a time of bonding. Many crave that. If someone is offering to be a mentor, this needs to be a priority.
