Sure, that seems like a smart optimization.

Yes that seems appropriate.

I guess that shouldn't happen (at some point the <addresses/> will be
gone and the stanza will go to a server rather than a multicast
component), but I think if a multicast component (which of course could
be part of a server) receives a stanza without an <addresses/> block it
would sent things to local addresses or return an error to the multicast
component. Could you provide a detail example of this scenario?

Return a <bad-format/> error.
