You would be seeing these regardless of SMTP or ESMTP or
pipe feeding.

The 8BITMIME only tells sending MTA that mail BODY may
contain 8-bit
characters with proper MIME content type. Mail HEADER must
not contain
any characters above 128 in any case. I don't think Postfix
converts
such characters to 7-bit even if it knows the receiving end
did not
announce 8bit-clean path.
