Just few ideas:

In the Server optimizations :
Could the server also cache reply to disco on some node ?
And the server would reply himself to the disco with known node, without 
routing the discovery <iq/> to the contact.
I guess this would also eliminate lot of traffic (i guess more than removing 
the caps from presences) (but i have not collected numbers)
Also the server would do the security check to eliminate poison client

About the security issue, what about using hashes ?

<presence>
  <c xmlns='http://jabber.org/protocol/caps'
     node='http://exodus.jabberstudio.org/caps'
     ver='0.9'  ext='foo bar'>
    <hash xmlns='http://jabber.org/protocol/caps#security'>
	** base64 hash of the concatenation of all nodes **
    </hash>
  </c>
</presence>



And last question:  Why is this protocol REQUIRED in the "XMPP Basic Client 
2008" ?   While it's a good protocol to have less traffic, basic clients 
should not require them IMO, because everything works well without it. maybe 
just RECOMMANDED
