It's for future-proofing.  Suppose you only wanted to export NFSv3,
that's all.  You could say "-N 2" and that would be fine ... until
NFSv4 was invented, when you'd need "-N 2,4".  Spelling it as "-V 3"
is more stable for the long term.

OK thanks.  A little doc patch might be helpful, if only along the
lines of "if you're not setting up firewall rules, these options
probably won't matter to you".
