While public-inbox is intended primarily for archival, SMTP list subscriptions are still in use in most places and users are likely to want a good unsubscribe mechanism. HTTP (or HTTPS) links in the List-Unsubscribe header are often preferable since some users may use an incorrect email address for mailto: links. Thus, it is useful to provide an example which generates an HTTPS link for users to click on. The default .psgi requires a POST confirmation (as destructive actions with GET are considered bad practice). However, the "confirm" parameter may be disabled for a true "one-click" unsubscribe. The generated URLs are hopefully short enough and both shell and highlighting-friendly to reduce copy+paste errors.
