The Lockdown extension was adopted in https://wiki.wikimedia.it/ to allow at least 4 read access levels (unregistered, registered, Ufficio, Direttivo).

Now we can try to drop it since we just need 2 access levels (unregistered, registered) since all the pages involved in the Ufficio and Direttivo are now deleted or published after T273607: Avoid storing secrets or private contents (e.g. readable by Direttivo-only, readable by Ufficio-only) on wiki.wikimedia.it not to require complex ACLs .
