There were a few premises driving the current (when you wrote this)
design:

        * Cluechaining is a way for backends to augment an incoming
        cluepacket with additional clues that might help other backends
        produce more and better matches.
        
        * New, chained clues can result in an augmented query which is
        not just broader, but also potentially more specific.
        
        * Backends should be stateless across a query, so that they are
        easy to write.
        
So the notion was that the rewritten cluepackets -- the ones with the
new, chained clues in them -- would indeed be redundant and contain
clues which overlap with old clues.
