Exactly.

This is what I was thinking about.  Alternatively we could rewrite all
message-id headers when we accept the message.  That would guarantee
uniqueness but it would break the correlation of message-ids between
list copies and direct copies.  Is that bad?  (note that we already do
this for NNTP posted messages, and there has been some off-list
discussion about that).
