RemoteAudioDestinationProxy base class is platform specific Remote proxies in general should work on all platforms. The platform specificness causes ifdefing. The ifdefing in the RemoteAudioDestinationProxy causes ifdefing for in RemoteAudioDestinationManager messages. Ifdefing in messages is problematic as the argument ifdefs cause new message names and that gets unmanageable. All this is because GStreamer does not yet use RemoteAudioDestinationProxy but still compiles it.
