Describe the problem you'd like to have solved

The subject was already raised in #147 but it's still present. Sadly, I see many interfaces, but the services are injected using the concrete class names (and the classes themselves are final), so decoration is still impossible.

You should instead inject the interfaces and leverage service aliases to keep the current behaviour. This way, the user can implement the interface with a custom class and then decorate the service.

Describe the ideal solution

For example, the Auth0\Symfony\Security\Authenticator class should be like the following

<?php

namespace Auth0\Symfony\Security;

use Auth0\Symfony\Contracts\Security\AuthenticatorInterface;
use Auth0\Symfony\Contracts\ServiceInterface;
use Auth0\Symfony\Contracts\Security\AuthenticatorInterface;
use Psr\Log\LoggerInterface;
use Symfony\Component\Routing\RouterInterface;
use Symfony\Component\Security\Http\Authenticator\AbstractAuthenticator;
// [...]

final class Authenticator extends AbstractAuthenticator implements AuthenticatorInterface
{
    public function __construct(
        public array $configuration,
        public ServiceInterface $service,  // <-- this is currently "Service" instead
        private RouterInterface $router,
        private LoggerInterface $logger,
    ) {
    }

    // [...]
}
