Well, I understand your point.
I think that now IPv6 is still used occasionally and many people may
built nginx --with-ipv6 just in store or may use a package built --with-ipv6,
i.e. they do not really want ipv6.

And if nginx will bind() to "[::]:80" by default, ulimate result will
depend on OS IPv6ONLY settings: on FreeBSD nginx will bind to "[::]:80" only
while on Linux nginx will bind to both "*:80" and "[::]:80".
