There is direct interface for that.

That is not quite true. route_stanza is supposed to be used for stanzas
not addressed to your component.

Override the process_stanza() method of the stream object.

Not to bother with subclassing you can just use some Python magic and
replace the attribute:

class Something(...):
    ...
    orig_process_stanza = None

    def some_stream_setup(self):
        self.orig_process_stanza = stream.process_stanza
        stream.process_stanza = self.my_process_stanza

    def my_process_stanza(self, stanza):
        if stanza.stanza_type == "route":
            stanza = do_something_like_stripping_route()
        return self.orig_process_stanza(stanza)

I hope that helps (haven't tried it myself).

Greets,
