Further development of the C++ plugins is not on our radar at this time 
beyond maintenance and fixing possible outstanding issues. It will also 
be next year until it will use the reduced precision mode of GEOS as was 
originally intended. That said, I'm happy to answer any question about 
the architecture of the plugin if anyone wants to extend it to 
eventually be able to replace the python plugins.
