I can't see why. The only real change here is to remove 
"no-fold-quote" from the "allowed to generate" syntax for message 
ids. (Of course we still require that they be interpreted.) I think 
this amounts to "removing an unused/non-interoperable feature", which 
is a *desirable* thing when moving to Draft.
