This has little to do with renumbering on the network to which the application is connected.   I agree that applications should do this, and that applications that don't will break if the provider renumbers, but we are talking about renumbering in the homenet, not renumbering of network services outside the home.

If you are referring specifically to naming in the home, while it's true that applications should support service address renumbering in the home, that is orthogonal to the question of whether services in the home should be numbered using ULAs or GUAs.
