If we take a step back, we could say that the whole Verisign incident demonstrated pretty clearly that the fundamental DNS premise of having no more than one root in the namespace is seriously wrong. This is the fallacy of "universal classification" so convincingly trashed by J.L.Borges in "The Analytical Language of John Wilkins". Sigle-root classifications simply do not work in real-world contexts.
... for objects which are created outside said classification and need to/ want to/should be classified in it. However, the DNS does not pretend to classify anything existing outside it in the real-world but implements a namespace with the stated goal of providing unique identification (which still requires a single-root)
Technically, DNS encodes the authority delegation, _and_ tries to attach human-readable labels to every entity accessible by the Internet.
If the goal were unique identification, MAC addresses would do just fine. No need for DNS.
MAC addresses are not without authority delegation. The IEEE is the ultimate authority in said case. Any solution which requires uniqueness also requires a singular ultimate authority.
