Release shape nodes from the requirement of having a transform parent.
At the moment, if a TD wants to implement a sequence of shape modifications, and then pipe them into a transform, they wind up creating lots of transform / shape pairs in the Outliner, because Maya loathes a shape without a transform. This creates a lot of redundancy and discourages procedural thinking.
Releasing this requirement would take us one step closer to the type of proceduralism encouraged by newer developments like offsetParentMatrix and component tags.
