What more value does this hold over implementing fluent interfaces which 
are already possible?

Assuming
class Foo {
    public function doSomething() { /**code**/ return $this; }
    public function doMore() { /**code**/ return $this; }
    public function doDo() { /**code**/ return $this; }
}

You can do this:

$bar = new Foo()
$bar->doSomething()->doMore()->doDo();

or, if you want exceptional fallthrough:

try {
   $bar->doSomething()
       ->doMore()
       ->doDo();
} catch (Exception $e) {
   ...
}
