Small mistake. If Upper case is used to denote primary, then for
consistency, the example should have been:
"w=S" (primary) or "w=s" (secondary) or "w=D" (mda)
The need for noting a signature added by the MDA is not the same as
that of sender would be important when the sender and the MDA share
the same domain. Perhaps the MDA signature encompasses a results
header added by the MDA at the edge of the recipient AdmD or AU.
This different role is needed to prevent an added signature from
allowing an exploit.
