Yes.  But I don't see how that affects this issue, here.

It makes the localpart content of the "Delivered-To" header a private
matter for the MTA that adds the header.  It need not identify the
mailbox to anything other than the MTA.

For purposes of loop detection the order in which "Delivered-To" headers
are added is not material, so requiring it to be prepended, as though a
trace header, may not comport with some existing implementations.  FWIW,
in Postfix it is in fact prepended.
