I think new projects from 2010 should not have ipv4-only. This time
should be over, finally. And people should get used to see ipv6
everywhere, and we should try to break the chicken-egg thing wherever
possible. :)

I can see the use for a systemd without any IP networking, but
compiling-out ipv6 seems like the wrong thing to me. Sure, we should
make sure, that systemd handles a kernel without ipv6 gracefully, but
not offer a switch to stay in the IP stone age. :)
