Hmm - the only discrepency I can see is maybe someone wants to run 
*virtual*proxies* for control reasons (proxy1.domain.com & 
proxy2.domain.com are one the same machine, so the Host: is either proxy1 
or proxy2) but I would consider having the header work through 1.0 
proxies to have a higher value.
