C++ overloaded functions could let the bindings do something different for objects that inherit ScriptWrappable from ones that do not in a generic way, without having to explicitly tell the bindings layer about the ways to do it. Consider the ways unwrap() and toJS() are done. We don't have to say anything special in the IDL or have any interface-specific knowledge in the bindings, C++ overloading takes care of it.

Good thought. ActiveDOMObject is a little different, because it implies some Web-observable behavior rather than just something about the mechanics of binding. But despite that, it's probably still better not to mention it in IDL if there is no technical need to do so.
