The scripts also, I think, hook up the eyelash morphs so they can be controlled from the figure. The Transfer Utility/AutoFit updates are certainly needed to cope with the new figure - see the entries in the change log on enabling the use of poses with the clones.

As with converting to another binding to get Genesis 3 to work in Poser, the result may be good enough for some users but it isn't the full feature set - that really does require a recent version of DS.
