运行PHP-FPM作为一个被监禁的linux是一个好主意吗?

I have a user tony who is jailed to his home directroy, from here there is a WordPress website being served. However, by default php-fpm is the user that is running the php-fpm daemon. This causes issues as php-fpm doesn't have the writes to tony's files, so WordPress can't self update.

If i change the user of a php-fpm daemon to tony, WordPress can self update.

Is there any implications of this? nginx is still ran as nginx, it's only php-fpm that i'm changing.
