What about adding a footer to some html mime part is poorly handled when using "l="? Multipart bodies could be handled by other techniques.
See section 8.2 in the DKIM spec which says if you use l= you need to be careful with your MIME boundaries so naughty people can't add another part that overlays the real message.
I have seen lists that edit the footer into the HTML of the body, I think at Yahoo groups. Don't see how you're going to describe that in a reversible way.
