Just picking a couple of points for further comment:

Robert is right, though, sending people to a long-expired draft is a bad idea.
Of course we have to acknowledge it, but maybe we should pull some of its text
into an Appendix.

Tim Chown, any opinion?

Yes, and check if it identifies any gaps that we should mention.

Bing: we should also add a reference to RFC 4085 "Embedding Globally-Routable
Internet Addresses Considered Harmful" which I missed for RFC 6866.

As Bing said, the *intended* scope is enterprise networks. We should
add that in the Abstract and Introduction. Indeed, many of the points
are more general.

Thanks again Robert!
