Reasonable user expectations. Most if not all uses of "PREPEND" are
headers that support desktop spam filtering or special handling in
downstream MTAs or content filters.

"PREPEND" is largely useless for MIME Entity headers and I can't think of
any useful semantics for PREPEND in the message body. One wants to tag the
header to indicate suspicious content in the body, but inserting into the
body is almost certainly both not helpful and wrong.
