我在我的Android应用程序中使用了一些对话片段，为了设置，我导入了“androidx.fragment.app.DialogFragment;“添加到每个DialogFragment类中。我没有将Fragment依赖项添加到应用的build.gradle文件中，应用稳定、工作正常，DialogFragments按预期加载和关闭。
由于DialogFragment扩展了Fragment，我是否应该将下面的AndroidX Fragment库添加到项目的build.gradle文件中？如果是，添加此依赖项有什么好处，因为应用现在没有它也能正常工作？

build.gradle

dependencies {

    def fragment_version = "1.5.5"
 
    implementation "androidx.fragment:fragment:$fragment_version"
}

Existing build.gradle (:app) 

dependencies {

    def room_version = "2.4.3"
    def lifecycle_version = "2.2.0"
    def work_version = "2.7.1"

    implementation fileTree(dir: 'libs', include: ['*.jar'])
