Environment::variables() empty on certain environments

[thekid]

thekid@Surface:~$ export | wc -l
22
thekid@Surface:~$ xp -w '\lang\Environment::variables()'
[]

This is because the ini setting variables_order doesn't include E for populating the $_ENV global:

thekid@Surface:~$ php -i | grep ini | head -1
Configuration File (php.ini) Path => /etc/php/7.4/cli
thekid@Surface:~$ grep -Er 'variables_order\s*=' /etc/php/7.4/cli
/etc/php/7.4/cli/php.ini:variables_order = "GPCS"
