Comment (by dgoulet):

 Hmmm yeah so because Tor can't extend to IPv6 then simply allowing only
 IPv6 in the INTRO cell is just plain wrong unless it is a direct
 connection (single onion).

 In other words, when the service gets the link specifiers and it is not a
 single onion, it should just ignore anything IPv6 *until* we have full
 extend support.

 I agree then, lets ignore this ticket for now until we have updated code
 on the single onion side and IPv6 support removed for now since Tor can't
 simply use it.
