Now, the initiator may not need to have such a stable identifier, since the initiator does not receive communications. what the initiator needs is an identifier that is stable during the communication lifetime so, if the locator change, the identifier is maintained so it is the communication. 

I agree in principle, but I'm concerned this is a theoretical
observation because I don't think we can build systems that
know what the lifetime of the communication is.

We do know. The lifetime is unlimited. A TCP connection can stay up as long as the two endpoints stay up.

The identifier needs to be stable at the endpoints as long as the endpoints care - which is why I like how HIP negotiates these labels, and maintains the mapping at the endpoints. The endpoints are the only place that can or should know about whether they change.
