I have kind of disagree here, beans.xml has a dedicated section for discovery (<scan>, spec section 12.4. Type and Bean discovery). I am trying not to (re)invent our own activation / discovery mechanisms but find the right way to deligate that to the framework in question. Not only CXF would benefit from that, the user's expectations would be met. Not sure this is possible, but I would be keen to explore this option.
