I think you're talking past each other here. I read SM's message as adding VBR-Info: to the list of known mail header lines here: http://www.iana.org/assignments/message-headers/perm-headers.html That seems reasonable. I agree (having talked to the same companies) that there is no point in making the header itself extensible at this point.
