Since it won't benefit the enormous base of existing poser content, I very much doubt it...

I do not see why they would not. Adding a new method of smoothing does not affect existing content. DS draws on the same base of existing content, and they did add this method, so what's different for Poser?
Advantages are evident, especially when it comes to morphs that would only need to define the morphs for the original points.
