can’t help you this side.
That new technology is “just” some layers/values linked in a Zelgadis magical way . You can have another inspiration of this way of using Synfig from “library of poses” thread
I’m not involved in coding synfig, but i can say that the next release will be 0.63.06, and no stable/intermediate version will be out until this one(if you dig the forum you can found some linux “snapshot version” who contain new terminology) … you need to wait, and you can help during you wait 
see(:ya!
