And bindv6only=0 is also not RFC compliant. However, a *lot* of applications
that use listening sockets will not work correctly anymore when you change the
default. So it probably is better to make it a release goal that applications
should work with bindv6only=1, and only if enough of them are fixed to change
the default.
