Need to see usage examples. It is difficult to understand what these classes are meant to do without seeing how they are supposed to be applied. The "design doc" will probably help here.
Either way, I don't think we'd want to include support for weak references, and I'm not sure we need to do anything special to increase the granularity of the topic subscriptions. A topic is just a class - it is up to the app to decide how coarsely or finely to define those classes to meet the needs of the application.
