Logging in Shopware 6 using Logger in a PHP file

I am not sure if this is the official best practice, but at least this works in Shopware 6 for example in a Subscriber.php inside a custom plugin:

• inject the Logger interface as a service argument
• receive the service in the constructor function
• service arguments and constructor paramaters must be in the same order
• define $this->logger in the constructor,
• so that you can use $this->logger->info etc. like in a regular Symfony project.

    <services>
        <service id="MyTheme\Storefront\Subscriber\FooterSubscriber">
            <!-- This must be in the same order as the constructor arguments in FooterSubscriber.php ! -->
            <argument id="logger" type="service" />
            <!-- ... anything else -->

FooterSubscriber.php

use Psr\Log\LoggerInterface;
class FooterSubscriber implements EventSubscriberInterface
{
    /** @var Logger */
    private Logger $logger;
        LoggerInterface $logger
    )
    {
      $this->logger = $logger;
    public function __construct(
