Trace headers have a long history... Are you sure this is "new" ?
Using Received: headers is certainly a possibility, but I think there may
be a problem with too many variations in existing formats, and the need to
cram in more information to support authentication protocols. As I
understand it, the format of the these headers is not adequately
standardized. If we try to define it more precisely, we may break existing
programs.
RFC2822 defines the Received header as follows:
received = "Received:" name-val-list ";" date-time CRLF
I can't find anything further on the details of the name-val-list. Has
this been formalized in some other document?
I assume the reason people developed new headers like Received-SPF was to
avoid these problems.
