It uniquely identifies the Ethernet interface in the (name)space of all existing and future ethernet interfaces. A locator has some built in topological significance. It is conceivable that any identifier could be used for a routing and forwarding in a flat architecture, where there is no aggregation based on topology. If we had no aggregation in IP addressing, i.e. if we had IP addresses free of any topological significance (like the ethernet addresses), then we would not have the current ID/loc split issue either. In a such system we could do all the multi-homing, mobility, etc. we wanted with more elaborate routing protocols. To summarise the point in the ID/loc split discussion is not about whether something can be used for routing and/or forwarding or not. The issue is with the built-in topological significance that limits the use of such "locator" to a somehow restricted topology, when we would want to have somehow different topology (more dynamic, multi-homed, etc.) instead. So the issue is about having identifiers free of network topological significance. It is yet another discussion whether these identifiers could/should have semantics on some other axis, e.g. whether these identifiers should be somehow structured for organizational (=administration/"ownership") reasons.
