Well, there's:

   6.   The injecting agent MUST NOT alter the body of the article in
        any way (including any change of Content-Transfer-Encoding).  It
        MAY add other header fields not already provided by the poster,
        but injecting agents are encouraged to use the Injection-Info
        header for such information and to minimize the addition of
        other headers.  It SHOULD NOT alter, delete, or reorder any
        existing header field except the Path header.

but I think you're right that message ID is special and needs a stronger
constraint than SHOULD.
