Symfony Event class deprecated (Drupal 10 error fired)

In a Drupal 10 CiviCRM instance I get this error using the Stripe extension:

Error: Class "Symfony\Component\EventDispatcher\Event" not found in include() (line 16 of .../firewall/Civi/Firewall/Event/FraudEvent.php).

The reason, here:

https://www.drupal.org/node/3159012

I hotfixed it doing:

//class FraudEvent extends \Symfony\Component\EventDispatcher\Event {
class FraudEvent extends \Drupal\Component\EventDispatcher\Event {

but I think it's not a suitable solution to pach here, because the CMS agnosticy of CiviCRM.

Not sure if:

class FraudEvent extends \Symfony\Contracts\EventDispatcher\Event {

could be OK. I think it is OK for Symphony 4 and 5, but not sure.
