Beyond even whether they subclass ServiceMBeanSupport, the question is whether they can function properly if deployed as simple microcontainer beans. Example, for a class providing functions like HASingletonController, as an implementation detail we may decide to subclass ServiceMBeanSupport and thus pick up some of its code base. But, if I don't need the controller to send out JMX notifications, it shouldn't require access to a JMX server to function.
