I already asked the question in the comment in one of the linked topics but it seems that the discussion is not monitored so I'm just gonna rephrase it here.
This was recently added to the SDK but it is not mentioned in release notes for September Playfab release.
This seems to address an important issue that is mentioned in few other threads like this one or that one. Official documentation also is a bit confusing because this tutorial is titled "Setting up PlayFab authentication using Google Play games" but it's not actually GPG auth (the thing added in commit linked above) but Google Account auth (old method which is affected by the linked issues).
Is there any official info on this addition? Can we use it to execute silent login with no oauth permission prompt caused by profile scope?
