You're right of course, see section 3.6:

    Field           Min number      Max number      Notes
    reply-to        0               1

(I'm battling a cold and lack of sleep so apologies for having been
lazy about looking it up.)

Are you suggesting that we collapse Reply-To: even if we don't add one
ourselves?  I would think that we should only collapse if we're adding
a value.
