Why would it? There isn't anything special about the link that would tell mailman to do so.
Ideally, people would have signature separators that would cause the footer to be trimmed, but that isn't mailman's job. (like Mark's did for me).

Should Mailman be stripping these out as part of its processing?

errr…. is this someone saying they would prefer I wasn’t on this list? I’d rather hear directly from someone if you feel that way.
Unlikely it's that. More likely, its because you've replied to posts without removing the msg_footer from the quoted material in your reply. See, e.g., <https://mail.python.org/pipermail/mailman-developers/2015-January/024152.html>.
Someone sees your post and thinks that's their unsubscribe link.
Be glad you didn't do what I once unthinkingly did at <https://mail.python.org/pipermail/mailman-users/2010-December/070723.html>. Every time Google, Bing, etc crawl that page, I get an unsub confirmation.
