Symfony Dependency Injection not triggering load function

问题

I'm trying out building my own CMS with the Symfony stack and I'm already in some issues with the Dependency Injection.

What am I trying to do
Load the 'Extension' of each module installed on the CMS, so services and doctrine settings can be merged.

What I am doing
Running Symfony Flex ( Symfony 4 ) I have in src/Kernel.php: ( in the configureContainer function)

foreach ($this->getInstalledModules() as $module) {
    $class = 'App\\Modules\\' . $module . '\\DependencyInjection\\' . $module . 'Extension';
    if (class_exists($class)) {
        $container->registerExtension(new $class());
    }
}

I have my modules stored in src/Modules/[module_name], the dependency loader for each module is in src/Modules/[module_name]/DependencyInjection/[module_name]Extension.php with namespace App\Modules\Articles\DependencyInjection

My extension for a module:

class ArticlesExtension extends Extension implements PrependExtensionInterface
{
    public function load(array $configs, ContainerBuilder $container)
    {
        die("LOADING");
        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__ . '/../Resources/config'));
        $loader->load('services.yml');
    }

    public function prepend(ContainerBuilder $container)
    {
        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__ . '/../Resources/config'));
        $loader->load('doctrine.yml');
    }
}

As you can see I added a die for testing purposes, the issue is that this does not get executed ( with or without the die ). The prepend function though gets executed and is working registering my doctrine entities accordingly.
