There is the method MongoClientSettings.Builder.commandListenerList that allows overwriting listeners in a MongoClientSettings.Builder in situations when, for example, the builder was created from a different MongoClientSettings instance as a template. There is no similar method in

• ClusterSettings.Builder for ClusterListener;
• ServerSettings.Builder for ServerListener, ServerMonitorListener;
• ConnectionPoolSettings.Builder for ConnectionPoolListener.

Not only this is inconsistent, but also diminishes the usefulness of the MongoClientSettings.builder(MongoClientSettings) method.
