But as I said, if you put all instances, that need to be named, in a subfile
of its own you *have* named instances. It wouldn't be too difficult to write
a helper program (or add-on) that does this folding for you (creating a
subfile of selected parts inside an MPD).

Objection. The MPD format gives one way of doing it.

Sure. It's necessary for animation, but I don't think the LDRAW format
should be used for instrumenting the animation itself. LDRAW is a format for
describing static models. Period.
To give life to those static models we need more.
MPD gives us a tool for creating a hierarchical model inside the existing
LDRAW specifications, now 'all' we need is another program which can read
such models, let us specify time line(s) for movable parts, models, scenes
or a whole movie and send the result into POVRay (or Blender or whatever).
I don't see any big logical obstacles in that route, only hard work creating
the program, and of course, first creating the specification for that
program...
