I wonder about a use case that is important enough that it is worth adding
quite a bit of protocol to every host.

My first question was, what if there is router on the link? In that case the
router could announce a ULA and there would no need for hosts to do anything.
Even if that would require extra protocol in routers then that would be
better than having all hosts implement an election protocol. I think
homenet already has a coordination protocol.

Okay, no router. In that case you would probably use some sort of
service discovery protocol, like mDNS, DNS-SD, etc., Would it really be hard
to pass a sockaddr_in6 around in an application? 

What else do we have. Debugging. There is a syntax for scope in link local
address literals. Maybe a bit more typing, but you don't want to type IPv6
addresses anyhow. There is a bit of a problem that browsers don't want to
implement that.

So the use case is not clear to me.
