manual modification after a list is created, the fix for this seems
to be to create a [plugin](https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/plugins/docs/intro.html), see [issue #41853](https://gitlab.torproject.org/tpo/tpa/team/-/issues/41853)
- Templates cannot be edited from the web interface, see [#41855](https://gitlab.torproject.org/tpo/tpa/team/-/issues/41855)
-[Cannot disable signups on lists](https://gitlab.com/mailman/mailman/-/issues/1088)
-[Xapian search engine uses up too much disk space](https://gitlab.com/mailman/hyperkitty/-/issues/533)
