That's a systemd file, no?
Mailman 3 core itself has never distributed a systemd unit file, although there are some suggestions about it in the documentation: https://docs.mailman3.org/en/latest/install/virtualenv.html#starting-mailman...
We could add that to the documentation as advice for MySQL/MariaDB users specifically, and generally for any external RDBMS.
Note that it should not be a problem for PostgreSQL, as PostgreSQL supports and recommends configuration with the systemd "notify=" setting.
