See <http://www.w3.org/Protocols/HTTP/1.1/rfc2616bis/issues/#i15>;  
there certainly isn't a brand-new MUST level requirement here (as  
there was a blanket requirement previously), and I don't see how an  
existing client could suddenly become non-compliant as a result of  
only this change.

Even if it were to, there is wiggle room enough in the charter to  
clarify instances where interop isn't possible, without changing the  
version number.
