Since I read about the Adroid's support for .aab file, I have been looking for a way to support this but all I found are "There is no support for this" and "Perhaps, next version of Godot would implement this".
Current Godot 3.2.2 stable doesn't support this yet and I cannot find any hint of support for this in v4.0 either.
I found Android's announcement saying:
Important: In the second half of 2021, new apps will be required to publish with the Android App Bundle on Google Play. (https://developer.android.com/guide/app-bundle)
Does it mean that we no longer will be able to publish mobile apps on Google Play in late 2021 unless Godot implements support for .aab files?
