I was surprised this wasn't checked by phpstan, as it usually catches issues like this. After looking into it, if I changed $input !== null to !is_null($input), phpstan does throw the warning. So for some reason PHPStan doesn't like the !==null .
Here's an interesting writeup on the differences between the two.
