The MIME RFCs work harmoniously with RFC 822 as every MIME message is a valid RFC 822

This is demonstrably false with regard to 8-bit and binary messages. From RFC 822:

     message     =  fields *( CRLF *text )       ; Everything after
                                                 ;  first null line
                                                 ;  is message body

     text        =  <any CHAR, including bare    ; => atoms, specials,
                     CR & bare LF, but NOT       ;  comments and
                     including CRLF>             ;  quoted-strings are
                                                 ;  NOT recognized.

     CHAR        =  <any ASCII character>        ; (  0-177,  0.-127.)

MIME is an extension of [2]822, which allows for more stuff than those documents. Characters above 127 do not belong in 2822[upd].
