Quote - It is my understanding that the DSON Importer converts DAZ's Triax weight mapping to Poser's more generic industry standard weight mapping.  If I am correct than Poser would need to add code to use the DSON format natively.

It does not do that. Poser's weightmapping is not Industry Standard, nor was it in Poser before Genesis was released. 

Yes, Poser would need to add code to support the DSON format natively, which is what I said, but it does not need to add DAZ Studio Code or be dependent on DAZ Studio.
