And mine as well. If LDView can correct for this then so can any other program.
The stud logos are a bonus feature offered by many programs but are not
officailly supported by the LDraw spec.

My problem with the studless subpart is that we'll set a precident that may be deterimental. What if we have 2 32x32 baseplates that are mirror images? would we have two files with 100+ stud that are exactly the same with the exception of the part being mirrored? This will only serve to increase render time since we mow have to parse and extra subfile.

I agree that this is a pretty petty reason for a hold vote
To sum up:
If LDView can correct for this, any program can. The extra work and subfile
clutter are just not worth it for a nice-to-have-but-not-required bonus feature.
