1. Does IIAB's apache_high_php_limits: False/True (as set in /etc/iiab/local_vars.yml) work with NGINX today?

2. If not, what's needed to get it working? This is needed by schools requiring intensive usage of WordPress, Nextcloud, Moodle etc.

3. Should the variable be renamed to high_php_limits to serve both Apache and NGINX?
