Even if it's not primarily intended for that purpose, Mailman is used extensively as (and can be configured as) an announcement list, vs. a traditional discussion list. In that context (where none of the members can post, or learn the email address of other members, and therefore won't accidentally post their unsub link to the list), it makes sense to have a one-click unsubscribe. While you might "maliciously" try to unsubscribe someone you don't like on a discussion list, there are good policy or legal reasons in certain cases to make *subscription* difficult, and *unsubscription* easy.
And as long as a 'Goodbye' message was mailed to the former subscriber, they would at least know they were unsubscribed... and if this happens and the former subscriber resubscribes, some kind of time based security measure could be used to prevent anyone from being one-click unsubscribed more than x times per [week][month][quarter][year][whatever]...
