A piece of mail is considered duplicate if it has the same message-ID

How about including Sender: into this determining factor? Sender: is set
to the mailing list address.
How would this help? Under what circumstances could an MTA send two
messages
with the same Message-ID vut different Sender headers?
What about messages without Message-ID headers? It wasn't that
many years ago that I got in an argument with an admin of a large
network that didn't bother to put IDs on outgoing messages -- as far
as he was concerned, external recipients/MTAs ability to disambiguate
messages wasn't *his* problem....
Fetchmail doesn't try to delete duplicates in that case.
