I've got something like this:

namespace App\Controller;

abstract class Controller extends \Symfony\Bundle\FrameworkBundle\Controller\AbstractController
{
    // some helper methods
}
final class FrontController extends Controller
{
}

This used to work fine, but I'm beta testing Symfony 6.2 and it's new PSR-4 Route loading and now I'm getting this message:

Annotations from class "App\Controller\Controller" cannot be read as it is
abstract in {"path":"../../src/Controller/","namespace":"App\Controlle
r"} (which is being imported from "/home/runner/work/qurplus/qurplus/config
/routes/annotations.php"). Make sure there is a loader supporting the "anno
tation" type.

This makes me wonder if extending the AbstractController is considered a good practice. Of course it doesn't contain any business logic, but only some helpers methods.

Is extending the AbstractController a good idea? And if not, what's the best way to organize these helper methods?
