Is "Sign in with Apple" compulsory as iOS 13 is released

Question

As per the AppStore review guidelines, now apps which are offering sign in with other social services also need the option of apple sign in.

4.8 Sign in with Apple Apps that exclusively use a third-party or social login service (such as Facebook Login, Google Sign-In, Sign in with Twitter, Sign In with LinkedIn, Login with Amazon, or WeChat Login) to set up or authenticate the user’s primary account with the app must also offer Sign in with Apple as an equivalent option. A user’s primary account is the account they establish with your app for the purposes of identifying themselves, signing in, and accessing your features and associated services.

We are planning to upload a new app with social sign-in options today which doesn't support login with apple id yet. So anyone faced any issues with review recently.

******Update******

9th April 2020 Apple sent email to all developers and informed about change in guidelines,

Please note that all apps that authenticate or set up user accounts must support Sign in with Apple if required by guideline 4.8 of the App Store Review Guidelines. New apps must follow guideline 4.8 and Human Interface Guidelines on Sign in with Apple starting April 30, 2020. App updates must follow these guidelines starting June 30, 2020.
