This makes me wonder if Link: in its reincarnation ought to be defined  
to be a response-header instead of an entity-header:

    The response-header fields allow the server to pass additional
    information about the response which cannot be placed in the Status-
    Line. These header fields give information about the server and  
    further access to the resource identified by the Request-URI. [RFC  

What would this break? I would guess that there are implications for  
CN and caching, but not sure  whether the change would be an  
improvement or damaging.
