Sorry not to announce it yet, but scoped addr format will
still change, like below.

   addr%scope

I'll send another mail to describe it in next to this mail.

When this change happens, those problems will be resolved.

Maybe your concern is that packets to the default interface
should be sent out to outside of host, at least?
On the other hand, I thought there should be some default
interface by default, but I afraid that an approach of just
choosing some interface as default interface might be end up
to choose non working interface.
But now I feel choosing lo0 approach is also somewhat strange.

So I'll try following approach.

  -"ipv6_default_interface" is empty by default
  -When all of "ipv6_network_interfaces", "gif_interfaces",
   and "ipv6_default_interface" are empty, then there will be
   no default interface
  -When "ipv6_default_interface" are empty but
   "ipv6_network_interfaces" and/or "gif_interfaces" is not empty,
   then choose one default interface from there.
