It is obviously a corner case which is not deserved such a high priority
(as high as a kernel panic or a compile error). bindv6only is default to
be 0, I even wasn't aware of such sysctl until David pointed it out.

So, please give me a reason why we should let such a corner case block
the inclusion? I think there are still other such corner cases too (and
maybe many), which neither you nor me are aware of.
