Note that X-BeenThere is essential to stop mail loops. My MTA puts Sender: headers in, Mailman just munges them to something more appropriate for the outgoing message.
X-Mailman-Version is arguably gratuitous, but it has been extremely helpful for me when people forward messages posted through a Mailman system. List-ID is a proposed or draft (can't remember) IETF standard, along with a bunch of other List-* headers we don't (yet) add.
I'd suggest leaving those headers alone and helping your users figure out how to get their MUAs to suppress these lines. I'd be surprised if they can't be easily hidden; most mail readers let you do this don't they?
