I'm guessing this trick was used to make arguments nullable for PHP prior to 7.1, but since Symfony now requires at least PHP 8.1 it shouldn't be necessary any more. As far as I can tell there's no breaking change: https://3v4l.org/USkgi .
There are still four places that this is used, but I believe those to be intentional test cases:
