The documentation says that there can be any mixed data attached to the current item.
This is clear. But how can this be applied in practice? I couldn't find any examples.

I did not use this miracle property, but you interested me, got into the kernel and dug up the following:
There is an addItem method in yii\rbac\DbManager

/**
     * @inheritdoc
     */
    protected function addItem($item)
    {
        $time = time();
        if ($item->createdAt === null) {
            $item->createdAt = $time;
        }
        if ($item->updatedAt === null) {
            $item->updatedAt = $time;
        }
        $this->db->createCommand()
            ->insert($this->itemTable, [
                'name' => $item->name,
                'type' => $item->type,
                'description' => $item->description,
                'rule_name' => $item->ruleName,
                'data' => $item->data === null ? null : serialize($item->data),
                'created_at' => $item->createdAt,
                'updated_at' => $item->updatedAt,
            ])->execute();

        $this->invalidateCache();

        return true;
    }

This means that when creating any item, and this can be a role or a rule, you can attach arbitrary data to it. For example:

$role = Yii::$app->authManager->createRole('admin');
$role->description = 'Администратор';
$role->data = ['roleColor'=>'#fff', 'razmer_sisek'=>5];
Yii::$app->authManager->add($role);

What would you use later, for example, to change the background or more useful things. Haven't tried it yet, but should work. Something like this:

<?php
$role = Yii::$app->authManager->get('admin');
$bgcolor = $role->data['roleColor'];
?>
<body style="background-color:<?=$bgcolor?>;">
