Why has Overstock/Medici/TZERO not used Ravencoin to tokenize any Medici company ?

I would have thought they would have used Ravencoin to tokenize at least 1 or 2 Medici companies by now considering how they helped develop Ravencoin.
I think it will happen in the near future and that is why I still hold Ravencoin.
Hoping American Films will use Ravencoin when they list on TZERO soon.
