Sub-parts are handled differently to primitives (from an authoring view
point). While primitives are generally not in-lined, sub-parts used during
authoring are often in-lined, if it doesn't increase the total file size of
the part too much. Having all the polygons in a single file is a slight
advantage when rendering.
