No, you misunderstand. Tor servers should be able to extend to other
Tor servers. While we keep that assumption, as long as there exists a
Tor server that only speaks ipv4, then all the other Tor servers need
to support ipv4 too.

And if they all support ipv4, then we're all set, end of issue.

So no, I don't think it's something that "needs" to be supported.
But all this said, it's still on our todo list. But it has low priority
since it won't get us much.
