Internally, hierarchical configurations use the NodeHandler interface to abstract over the concrete node model. That way other hierarchical structures can be handled. However, the most important use case is to access hierarchical structures via the Configuration interface. Node traversing is a rather low-level operation, and so far there has not been the need to offer better support for this.
