Comment (by neel):

 Replying to [comment:10 AVee]:

 > Can you explain to me how this makes 3 and 4 worse, compared to the same
 relay running a normal dual stack? Unless i'm missing something here about
 the internals of Tor (which could well be the case) any progress on 2 will
 have a negative impact on 3 and 4.

 Not teor, but I believe this would:

  * Add overhead to IPv6 connections as they would be routed to IPv4. On
 top of this, you won't really have true IPv6 sockets as much as IPv4
 sockets routed to an IPv6 address.
  * Possibly make the consensus harder to calculate with a non-standard
 configuration.
