Why cache:config saves data only from .env file?

[xorock]

Any variable in your .env file can be overridden by external environment variables such as server-level or system-level environment variables.

This lead to inconsistency and unpredictable behaviour. For example

shell -> export APP_NAME=Testing
config.php -> 'name' => env('APP_NAME', 'Laravel'),
echo config('app.name'); // Testing
php artisan config:cache
echo config('app.name'); // Laravel

Shouldn't cache:config command merge both values - first check if it wasn't overridden - if so, use it, if empty use value from .env?

export doesn't work but the following does.

➜  dusk-suite git:8.x ✓ APP_NAME="Testing" php artisan config:cache
Configuration cache cleared!
Configuration cached successfully!
➜  dusk-suite git:8.x ✓ php artisan tinker --execute="echo config('app.name');"
Testing<aside>⏎</aside>
