It helps clients configured to use dual-stack IPv6:
ClientPreferIPv6ORPort 1

And clients configured to use IPv6 only:
ClientUseIPv4 0
UseMicrodescriptors 0

But as they are manual configs, not many clients use them yet.
We want to make dual-stack easier (even automatic) on clients, but we
need more IPv6 relays to preserve client privacy.

Yes, but you need to keep *both* addresses for 2 years after you add
IPv6. Let me know, and I'll add the IPv6 address to the fallback list.
