It certainly was causing a lot of pain and that's why I decided to get rid of kernel autoconf entirely some time ago and also why other developers agreed with me. They have recently updated this decision with a bit of more cooperation regarding temporary addresses and added kernel features for that. > > This isn't supposed to be a war between kernel and userspace. NetworkManager is often the main driver for kernel network configuration features. You are welcome to install and test a git snapshot of NetworkManager and/or participate in the development. > We've actually been doing that, for example with the IPv6 tempaddr > changes that recently went upstream.

At least not some specific details like changing the metric without disturbing network communication, and also the specific way of choosing the metric. In my opinion, the kernel is not yet mature for this kind of operation.
