No-one is working on it, as far as I know.

That just changes the IPv6 address selected by the OS.

I can't see how it's relevant - unless you have *not*
configured privacy extensions, and so autodetection
exposes your MAC address to the world.

No, Tor ignores private addresses during autodetection, and
relies on other relays to provide the external address.

This only works for IPv4, because relays almost always use
IPv4.
