Im working on a game that uses google drive android api to store save games into app data folder. Now i want to migrate everything to REST api, since gdrive android api is deprecated now, but i noticed very strange statement in deprecation notice here: https://developers.google.com/drive/android/deprecation
"Support for storing and syncing in the app data folder will likely be removed from Drive in the future. Clients requiring app data storage are strongly encouraged to migrate to a non-Drive solution such as Cloud Firestore."
Anybody knows more concrete timeline for app data deprecation apart from "will likely be removed"?
Question is if it's still reasonable to invest time to migrate savegame storage to rest api or to just switch to Cloud Firestore as suggested.
