ip-precedence for management traffic

Totally out of the box, but here goes:  why don't we run the entire Internet management plane "out of band" so that customers have minimal ability to interact with routing updates, layer 3/4 protocols, DNS, etc.?  I don't mean 100% exclusion for all customers, but for the average Joe-customer (residential, business, etc., not the researcher, network operator, or clueful content provider) do they really need to have full access to the Internet mechanisms (routing, naming, numbering, etc.)?

We already provide lots of proxy services for end users, so why not finish the job and move all of the management mechanisms out of plain sight?

Agreed, it's very important to have a management network that is reachable while you are under ddos or some kind of mess you or someone else've created. Often having something like an ADSL like connection will save trips to colo and will give you nice abilities to work on stuff when combined with serial management tools.
