The Config namespace is pointless and merciless.

The Autoload config makes it possible to define namespaces. In particular, the Config namespace is already defined and can in fact be changed.
At least that's how it was intended, I suppose.

PHP Code:

    public $psr4 = [
        APP_NAMESPACE => APPPATH, // For custom app namespace
        'Config'      => APPPATH . 'Config',
    ]; 


No, we cannot change the namespace Config.
We can change the App namespace only.
