While your answer to the question I was trudging through dozens of comments to get to (not worth a sentence in the article?) was quite long, I don't think it was sufficient. I think your answer was still within the debate of 'should the move happen'. But what I think the original ducking questioner was asking was-
If you are one of the people who believe in moving /* stuff to /usr/, then please explain why you specifically think that is better than the opposite of moving /usr/* stuff to /, as that would achieve shorter paths, and since, at least from a limited perspective, _once you are in the usrmove camp_, it seems hard (unless us duckers are missing something obvious) to explain what the point of /usr is at all.
