Because - as you noted - these extensions are not part of the RTSP standard, we don't support them.  Also, unfortunately, it would not be possible to support them without modifying (not just subclassing) the existing LIVE555 library code.  In particular, you would need to reimplement the "MediaSubsession::initiate()" function.  For 'backchannel' subsessions, you would need to create an appropriate "RTPSink" subclass, rather than a "RTPSource" subclass that the existing code always does.
