Yes, definitely IMHO).  The problem here is not the lack of  
understanding of
what could be done (writing the C code for these primitives is actually
quite simple), the problem is more like there is not enough resources
to finish the modular infrastructure Gary started.  Once the  
infrastructure
finished and released, it should be quite straightforward to use it.
