You're welcome. Unfortunately, LibreSignal was shut down due to: https://github.com/LibreSignal/LibreSignal/issues/37#issueco....

I wouldn't pin too much hope on having a high quality PR written and integrated back to Signal soon. It doesn't look like a top priority for them. OWS also like the telemetry that Play gives them for diagnostics and have stated they won't be looking at FDroid unless someone can replace that.
