That's a point.  The confusion would only arise though if there were
multiple recipients on the local machine.  However...

Multiple BCC deliveries to one host require an equal number of distinct
SMTP sessions, since the BCC recipient is specified via the envelope RCPT
TO: and that can only be one address, correct?  Therefore, this header
could be named X-Original-BCC (or somesuch) and applied in the case that
the envelope recipient does not match any of the To or Cc addresses.

Even better though, could this whole situation be resolved by simply
providing more information in the Received header?  For example, on your
message to which I am replying the last Received line is this:

Received: from mx-outbound.sourceforge.net (mx-outbound.sourceforge.net
[66.35.250.223])
  by basil.zygoat.ca with esmtp; Fri, 31 Dec 2004 07:12:09 -0500
  id 00018CCA.41D54219.00007F1B

If this instead read "... by basil.zygoat.ca for [EMAIL PROTECTED] with esmtp
..." that would precisely give the missing information.

My understanding was that there was no canonical format for Received
lines, so this would pose no problem.  If I'm wrong, then another header
(X-Envelope-To or whatever) would fill the bill.

Am I still missing something?
