-------------------------------+-----------------------------
 In PHP 8.4, declaring function/method parameters with a default value of
 `null` is deprecated if the type is not nullable.
 [https://wiki.php.net/rfc/deprecate-implicitly-nullable-types RFC] and
 [https://php.watch/versions/8.4/implicitly-marking-parameter-type-
 nullable-deprecated PHP 8.4: Implicitly nullable parameter declarations
 deprecated]

 Out current minimum PHP requirement is PHP 7.0, but nullable types are
 only supported in PHP 7.1 and later.

 Submitting the PR with the fixes and to start a conversation, but merging
 these changes without bumping minimum PHP requirement to 7.1 will break
 things on PHP 7.0.
