SPF support is explicitly included in the list of methods supported by 
the draft.  If other additional wording is needed to indicate that this 
would replace the Received-SPF header in RFC4408, can someone propose 
such? I'm not sure off the top of my head what language might be 
appropriate.

The current wording is meant to acknowledge that Received-SPF exists, 
but is not sufficiently universal for general use.  Personally I think 
that's sufficient.  I don't think we need to officially deprecate it; as 
Scott indicates, one could use either or both in an SPF implementation.
