[MariaDB packagers] MariaDB default users, databases and permissions in various distros

Hi! There are a lot of guides online that recommend running mysql_secure_installation (or MariaDB equivalent mariadb-secure-installation). On Debian/Ubuntu this script is pretty much useless, but in https://dba.stackexchange.com/questions/346696/should-dbas-stop-running-mysq... a commenter pointed out that in Fedora there are still anonymous users and a test database created on the default install. I wanted to check here on the packagers list what is your take on this? Should we try to unify that the default users and databases across various distros and packages of MariaDB would always be the same (secure) defaults so that mariadb-secure-installation can be deprecated? - Otto
