为什么设置首页的热卖商品和特色商品，不能在后台产品信息中设置呢？而是在配置文件中设置，我觉得很奇怪，这是什么原因呢？

return [

'cms' => [
    'params'=> [
        'home_title'            => [
            'home_title_zh' => 'mall',
        ],
        'home_meta_keywords'            => [
            'home_meta_keywords_zh' => 'mall',
        ],

        'home_meta_description'            => [
            'home_meta_description_zh' => 'mall',
        ],
        'homeBestSellerSku'        => [
            'ad001'
        ],
        'homeFeaturedSku'        => [
            'ad001'
        ],

    ],
],

];
