The 'N' (Node) field in the message database has been resurrected, this time as a flag to indicate that a message originated on the local system, as opposed to an inbound email or some other nonlocal source.  This field is not populated yet.  If old messages with CitaNet remote nodes are discovered by the new code, the desired behavior should still work (suppress display of RFC822 email addresses)
