Please have a look at https://schleuder.nadir.org/docs/#an-email-hub-for-groups about the context here of remailing.

So correctly it should have been called resending.

gpg-remailer explicitly does not want to be a mailinglist, so it differentiates in multiple features (no mgmt of subscriptions of a list over list commands) nor does it have features like remailing capabilities.

schleuder is not a replacement for GNU Mailman, it does not contain all the features of GNU Mailman, while adding certain other features (e.g. remailing) that are not part of GNU Mailman.
