 Review comment:
   For example, check this popular Ansible role to install Airflow:
   
   
https://github.com/idealista/airflow-role/blob/master/tasks/config.yml#L23-L35
   
   It uses **0640** permissions just for **airflow** user and **airflow** group 
and is run via systemd.
   
   So no other user can edit/view this file.
