I do not agree with this change.

IPV4 is a lot different from ipv6, for example ipv4 lacks things like
temporary address assignments and other notifications that links listen
to even if they don't have explicit static addressed assigned.

The ipv4 behavior also has two decades of precedence, and I think you'll
have a very hard time convincing me that nobody depends upon it.

So I'm not applying this patch, sorry.
