Why name behaviors in Yii2?

Question

Yii

Hello!
Why are behaviors named? Example from yii\filters\AccessControl documentation:

public function behaviors()
{
    return [
        'access' => [
            'class' => \yii\filters\AccessControl::className(),
            'only' => ['create', 'update'],
            'rules' => [
                // deny all POST requests
                [
                    'allow' => false,
                    'verbs' => ['POST']
                ],
                // allow authenticated users
                [
                    'allow' => true,
                    'roles' => ['@'],
                ],
                // everything else is denied
            ],
        ],
    ];
}

In the documentation I found information only that there are named, and actually not named (anonymous) behaviors and that's all. Thank you.

the use of named behaviors allows you to:
1. Detach the behavior from the component, if necessary, using the detachBehavior function
2. Work with the behavior in descendant classes (for example, change the behavior configuration, etc.)
3. Get the behavior object itself and, if necessary, with it work
