I've only seen them a couple of times, and that was over ten years
ago, with addresses that gatewayed into X.400

Yes, you're right, that would probably be enough.

Gatewaying is the only context in which I can recall seeing them.  So

they can consider these issues when they decide how to map addresses
into the Internet world.
