It seems quite reasonable to me.  My only comment would be on section 2:

My understanding is that it is an acceptable, but less common,
implementation choice to allow Bcc recipients to see each other; that
is, the message text sent to Bcc recipients MAY include a Bcc header
listing all Bcc recipients.

RFC 822 says:

    4.5.3.  BCC / RESENT-BCC

        This field contains the identity of additional  recipients  of
        the  message.   The contents of this field are not included in
        copies of the message sent to the primary and secondary  reci-
        pients.   Some  systems  may choose to include the text of the
        "Bcc" field only in the author(s)'s  copy,  while  others  may
        also include it in the text sent to all those indicated in the
        "Bcc" list.
