Support for "Sign In with Apple" in fall 2019

According to https://developer.apple.com/news/?id=06032019j, support for "Sign in with Apple" will be mandatory for all apps that support other third party logins:

Sign In with Apple will be available for beta testing this summer. It will be required as an option for users in apps that support third-party sign-in when it is commercially available later this year.

If this remains true, it means that apps using FirebaseUI Auth with Google and/or Facebook will probably be rejected starting sometime in fall this year if "Sign in with Apple" is not a supported option.
