I also reckon a SHOULD is better for the message-ID.  It would prevent duplicates
from being posted in case the same proto-article is posted twice (therefore sent
to the moderator with the same message-ID).  Useful for both auto-moderation bots
and manual moderation.

And they are encouraged to retain the Date: header (no need for a SHOULD here).
