That's not quite true.  It's true that the user herself needs the
replied-to message ID to thread, but if she replies to a message
without the message ID, she breaks threading for everybody else, too.

I'm sorry I missed the point about text/plain digests, though.  True
enough, in that case there's no need for Content-Type.
