MetropleX Regarding this bit from the project FAQ:
Our compatibility layer supports the Play Store updating itself and also Play services but we've chosen to block it from being able to update them in order to ship the updates through our repository after testing them. They use long staged rollouts for these app updates and it results in confusion when users can't install older versions in another user, which is resolved by us handling the updates ourselves.
Is that to say the installation is blocked only via the Play Store, and that the Aurora Store and other sources could update it if the user isn't careful?
