It's only required for Drawables and StateSet's, changes to Nodes don't make it into the draw traversal so aren't affected by the requirement to set the DataVariance to DYNAMIC that the DrawThreadPerContext threading model requires. If you plan using the osgUtil::Optimizer on your data then the DataVaraince value is used as a hint about what can safely be optimized and what can't be, for instance a DYNAMIC transform node can't be optimized away. This is unlikely to be an issue for in frame updates.
