Nonetheless there is the same complication. I like to test 
"half-instantiated"
objects (maybe this is common/best practice?):

<?php
class C {
     public string $a;
     public string $b;
     public function __construct($a, $b) {
         $this->a = $a;
         $this->b = $b;
     }
}

// test only a
$c = new C("foo", null); // fail
var_dump($c->a === "foo");

// test only b
$c = new C(null, "foo"); // fail
var_dump($c->b === "foo");
?>

So if i want typehinting, i have to add "= null" without any real benefit as
for testing. Current behavior doesn't restrict NULL values. Why change this?
"method-like optional values"?
