Kyle, I don't know if you can see this from where you're sitting, but you
are making a religious argument here. It is not a misconfiguration to put a
ULA in the DNS right now in the sense that it causes a problem. It's a
misconfiguration because it doesn't match your mental model of How Things
Should Be.

I don't entirely disagree with you about this—I don't think that we ought
to put ULAs in the global DNS. But I don't actually have a solid argument
against Lorenzo's position—I just don't happen to agree with it.
