What exactly does that change?
$a = "foo"; list($b) = $a; var_dump($b);
This is weird... I wouldn't go as far as saying nobody uses it - since experience shows there's somebody somewhere using any weird combination of PHP features imaginable - but it's definitely a strange code. Even though, I think since it's functionality drop, we may want to wait with it, unless it doesn't work anyway (e.g. produces segfaults in some cases).
