Concur - I think codifying DNS's dynamic structure in an outside medium is only going to cause problems down the road (e.g., especially with namespace diffusion from the likes of new gTLDs, etc..).

While an unfortunate naming collision here (i.e., the "SOPA" RR), I think an approach such as [1] has some merit - but much work needs to be done.
