Is there any reason why \Symfony\Component\Security\Core\Exception\AuthenticationException does not implement \Symfony\Component\Security\Core\Exception\ExceptionInterface?

I would like to be able to catch all kind of Security related exceptions simply by using

} catch (\Symfony\Component\Security\Core\Exception\ExceptionInterface $sex) {

and I'm not able to catch for example \Symfony\Component\Security\Core\Exception\BadCredentialsException using that catch

Cheers.
