I use quiet advanced tools for models to make them universal, actually would not be a big issue for creators with experience. So I just give it a shot at renderhub if it is causing some other poser creators to share there creations then it is only positive, if not and the assets are just remaining as storekeepers, then it just would not have to be. Quiet simple! It can be seen rather fast in a store weather it is worth or not, with a few different theme releases also looking at the hits of other Poser creators and likes, the interests can be estimated this way.  the only thing that can be done is to give it a shot. 

A creator normally stops supporting a platform if end users , customers are leaving, Creators fallow the Interests of the ones who invest in there work, it has not much to do weather a platform is better or not.
