OK, so that leads to one of my desires in an upgraded (or different) GDL:
level-of-detail control. Basically, there should be language elements that
allow authors to flag the priority of different elements in a file -- so the
main outside body of a brick could be flagged as high-priority/low detail,
the studs could be flagged as medium, and the insides could be marked as
low-priority. That way, when fast-drawing is required, only the
high-priority objects would be rendered. When high-quality rendering is
needed, all objects would be rendered.
This isn't a new idea -- I believe it's in the LDraw II papers.
