MariaDB already ships a “unix_socket” authn plugin by default. All the admin has to do in order to gain access to a user’s data is to enable that plugin for the user, drop privileges, then log in.

Arguably, this is just a default-configuration change that I’m suggesting: configure root@localhost to use unix_socket authn by default (on Linux).
