I raised a bug against a document once, only to be rebuked. I had (another) look at the wiki. You're right, it seems to describe NFSv3 only. I don't have NFSv3 here to compare. With NFSv4 you export the global root directory to allow its subdirectories to be exported too - at least this is how I understand it works on my systems.
