I would expect a single 2001:0000::/32 route leading to the closest
teredo relay.

Only a tiny fraction of the traffic goes through the servers. The bulk
of it goes on a direct IPv4 path between the relay and the Teredo host.
The benefits of "per server' /64 routes would be marginal and the impact
on the routing tables would be large.

Yes. With this design, traffic will go from IPv6 host to the closest
Teredo relay and from there on a direct IPv4 path to the Teredo host.
This is expected to be a good approximation of the shortest path between
the IPv6 host and the Teredo host.
