CakePHP: List all Controllers using Component X

Question

Long story short: How do I get all controllers of my app that use a certain component.

The story: I have multiple controllers in my app, some of them using a component.

public $components = array('MyPlugin.MyComponent');

Is there a way, in the component or elsewhere, to find out which controllers include this component so I can list them?

Turns out it seems to be quite simple, but I am not sure if this is the correct way to do it, as it seems pretty hacky to me:

$controllers = App::objects('controller');
foreach($controllers as $controller) {
    App::import('Controller', str_replace('Controller', '', $controller));
    $properties = get_class_vars($controller);

    if(isset($properties['components']) && (isset($properties['components']['MyPlugin.MyComponent']) || in_array('MyPlugin.MyComponent', $properties['components']))) {
        $this->editable[] = str_replace('Controller', '', $controller);
    }
}

Any better solution out there?
