Exactly. That's what abstraction layers do; hide the details of the layer
below. And the most useful ones are evolutionary, i.e., you only need to
adopt them as needed. IP abstracted Ethernet (& other LAN protocols); DNS
abstracted IP addresses; and XRI abstracts URLs & URIs, and each can be
adopted incrementally as the need (like the one being discussed here for
simple identity addresses) emerges.
