Yeah, I think you may be right.
However, I have never tested it either that I can remember.
I thought I had made a wall segment transparent before, but it must have been an entity. (memory failure again. sorry)
I could have sworn that the rgb 0,0,0 worked on a ground segment before, but it wouldn't work when I just tested it.
What does work on the ground segment is a transparent (blank) texture.
It showed up as white in the editor but it was transparent in the test build.
Like I said I haven't played with it much either, but if it doesn't mess things up then could it possibly give skybox views without FPS loss?
You can find the answers to the mess up question faster than I can since you play with the source.
