I'd be even more conservative.  That is, if an application handles A-R
fields, then it should produce those instead of Received-SPF.  Otherwise, it
may use the latter to communicate results to a downstream agent.  This way,
programmers should read RFC 5451 if they want to implement it, not just
blindly replace a header field with another.
