PHP-FPM not Default to /etc

Hello Friends

I am following the tutorial on PHP-FPM, link below:

https://docs.01.org/clearlinux/latest/tutorials/php.html

I am curious if there is some reason why by default php-fpm does not look for additional configs in /etc?

For example, the default could have:

include=/etc/php-fpm.d/*.conf

or

include=/etc/pool.d/*.conf

in:

/usr/share/defaults/php/php-fpm.conf

This make is easy to run different PHP applications as different users, see link below.

This approach seams very much in line with Clear Linux’s Stateless environment idea. It seems odd to me that it is not there by default and make me wonder if I am missing something.

Thank you
