You know what? I actually agree with Nico on this.

It's 2019 and the adoption of IPv6 is actually gaining momentum (at last).

This is absolutely the time to seriously start thinking about unbundling 
IP-stacks the kernel, so that IPv4 can be truly disabled at compile time.

That will allow for further testing and fixes, just as Nico suggests.

I couldn't agree more.
