All this discussion is fun, but what about:
1. Bind implementation enforcing character set restrictions should be observed by system configurators.
Isn't a resolver library purposefully junking not exactly correctly formed domain names in a direct contradiction with the paragraph 1.2.2 of RFC-1123 a.k.a. STD-0003?
2. DNS delegations are just that. Businesses name entities within their naming context in a manner that suits their business purpose. Within their own context (and the RFCs) a business sets its own naming rules.
Note that this does not rule out being cooperative and sensitive to the needs of others. But that is the prerogative of the owner of the delegated naming context. That is the essence of "delegation" in DNS.
Exactly.
