RFC 934 style attachments, as practiced by burst(1), were far easier to forward. if you just included the raw text (headers + newline + body) then all the attachments went-with.

MIME broke all that. a lot of UI's can't cope with attachment trees where one rfc822 includes another which has attachments. the way modern graphical MIME UI's work is by iterating down through the forwarded message's MIME tree and attaching each attachment to the top level of the forwarding message. this is quite destructive, and complicated, and expensive. but it's what forw(1) would have to do.
