Pretty much yes.  Since extensions can do all kinds of things (set properties, add interceptors,
etc…) which would be difficult to "undo", it's not something we've tackled.

If the extensions are not really loaded via a META-INF/bus-extension.txt and instead are OSGi
services, you may be able to accomplish a bit more.   When the bundle stops and the service
is stopped, it should be able to get a blueprint lifecycle event and then go ahead an unregister
anything that is may have registered, but I'm not 100% sure that would work completely correctly.
