Hmm, I see your point. Except that the desired orientation of a subfile
may be known before that subfile is certified. Here's a (somewhat
contrived) example: we've discussed defining the standard orientation of
all primitive files to be outward and upward. So, we know what direction
4-4disc.dat is going to face, even before it's certified.
Even non-primitive subfiles may be in the same situation: the author knows
what the orientation is going to be, but hasn't cleaned up the subfile yet.
