/// be modified without going through a full cycle of server
/// reconfiguration, e.g. add a subnet to the current configuration as
/// a result of receiving a command over control API. In such case the
/// performance of processing such command is critical and rebuilding the
/// whole configuration just for this small configuration change is out
/// of question.
/// Nevertheless, such configuration updates should always be made with
/// caution and one has to make sure that the configuration data integrity
/// is preserved.
