This is why I'm very much not too motivated to integrate changes like this, even though I understand the motivation and simplifications this would enable. I mean, who the heck are we to tell someone that because they make some tiny device meant for an isolated ipv4 environment that they _MUST_ have ipv6 also built into their kernels? Seriously...
