It would be good if anyone that actually uses durable sockets explains
their use cases. The one solid usecase I have for explicit identities
is router-to-router connections, as in the Freelance pattern.

That's needed for peer-to-peer routing. It could be solved by using
schemed identities (as already discussed) since this lets a sender
guess the identity of a receiver in advance. You can see the
argumentation here:

Without some way to route speculatively, certain valuable p2p
topologies become impossible.
