Why do you need to create a separate admins.php entry file?

Question

Why do we need to create a separate admins.php entry file? Isn’t it better to use index.php directly?

Answer 1

is generally used to distinguish between the backend and the frontend. admin.php can set groups or controllers directly to the background groups or controllers. If you use index.php, you also need to add the controller address, which is more troublesome.
