Well, this would provide a very rudimentary code for transformation hierarchies, nothing more. In fact, you can already do this with osg::MatrixTransforms or some subclass of them - a bone is nothing more than a transform, plus some extra data for skinning. However, it doesn't solve any of the animation and skinning issues and is completely useless by itself. I cannot imagine somebody "bringing it up to speed with other kits" from this alone, for that you need something actually usable to start from. This is why e.g. osgCharacter is a toy only - it does exactly this. You could display a "stick-figure" character, but that would be about it. I do not see why somebody would spend time on this when he can use osgCal or Replicant that work already?
