Since you asked on list, I'll reply, but I don't think this is the right list to pursue this discussion and if we're going to have to do that I suggest perhaps DNSOP or the dns-operations OARC list or perhaps dnsext@ietf.org (which is still open), depending on whether you want to talk about protocol or operations.

Nothing, in principle. In practice, it depends. You might want to have a look at RFC 6912. Even though it was particularly about Unicode code points for U-labels, the general principles outlined there are useful in other ways too. > P.P.S. Exactly what is wrong with a terminal label consisting only > of characters in the 0-9 range, that is not completely cured by a > requirement that the next subordinate label contain one or more > characters from the range g-z? Well, the actual terminal label cannot contain any characters at all, but I think you knew that and meant the second-to-last label (conventionally called a TLD). So, first, there's actually no technical way to require what you're saying, really. That's what "delegation" means. You could do it with contracts, though. But what you're really saying is that the heuristic implied in RFC 1123 might break. That seems like an extremely incautious thing to do, and therefore a responsible operator of the root zone wouldn't do it. Technology is not infinitely plastic: once you have deployed something, it affects the world. In the case of the DNS, the way it has affected the world is partly based in the assumptions people have about what their software may depend on.
