New description:

 In teor's comment in #31088:

 > You've added some code that isn't needed yet. Please reject all IPv6
 extends in this patch, and open a separate child ticket of #24403 for
 allowing IPv6 extends.

 Edited to add:

 When we add support for IPv6 extends, we should check for internal IPv6
 addresses in extends. And we should check for internal IPv6 connects on
 non-bridge clients, relays, and authorities.

 ExtendAllowPrivateAddresses should disable these new checks.
