By default this prevents Weblate from granting access provided by Users and Viewers default groups due to these groups’ own configuration. This doesn’t prevent you from granting permissions to those projects site-wide by altering default groups, creating a new one, or creating additional custom settings for individual component as described in Custom access control below. One of the main benefits of managing permissions through the Weblate user interface is that you can delegate it to other users without giving them the superuser privilege.
