Description

See https://github.com/WhisperSystems/Signal-Android/issues/6895

The only way to test for the presence of GCM is to make the framework call that we're making, which MicroG is apparently returning true for. You can re-enable MicroG after registration and Signal will not attempt to use GCM.

Could this be implemented?

Research direction

Start by reading the linked Signal-Android issue and the quoted behavior around GCM presence checks. Then locate the GCM registration and framework-call handling in GmsCore; done should mean the specified apps are prevented from using GCM while other registrations continue to work.
