Oh, there is nothing with TRAVERSE's output _right now_.

Let me clarify this again:

- The fact that TRAVERSE now adds the same operation for all components was new. That was my source of confusion. Before this did not happen with LIB-OP and the like. Maybe a straightforrwad solution is just writing

(defun perform ((o bundle-op) (c component)) nil)

so that all components which are not modules get a default PERFORM that does nothing. Is this safe?

if the library adopts an ansi-11.1.2.1.2-like restriction on extensions, this would be compatible, because one of the specializers is not a standard class.
