Sounds like an argument /against/ allowing part of a message to be  
signed, and part not.

By having a body length parameter as part of the DKIM protocol,  
whenever offered by the signer, users can employ MUAs that properly  
indicate which portions of a message originated by the signer, and  
which did not.  This might be done by distinctively enclosing the  
included portions.  Often appended comments mess up page formatting  
whenever lines extend beyond the edge of a page.  Don't you hate  
that?  Currently, use of RFC 5451 allows providers to include anything  
they wish, while still purporting the entire message to have been  
originated by the signer.  This is wrong, regardless of any number of  
providers demanding MTA that offer such a dubious feature. :^(
