Well, we could have the current activator grab a list out of the current bundle (cxf-bundle) of other activators to instantiate and call. For example, we could have a META-INF/cxf/osgi-activators.txt that is created during bundling (shade can do it) that the OSGiExtensionLocator thing will grab and then call the start/stop on it. We'd only need to look in the current bundle. Once we split into modules, the "core" bundle would not have that and thus wouldn't do anything, but the jaxrs bundle could properly define it's own activator in it's manifest. This wouldn't be hard to do.
