I agree this should be killed.

As a sane alternative, maybe it makes sense to add a "disable" node as

interfaces ethernet eth0 ipv6 disable

That would set the sysctl, which is far more sane:

net.ipv6.conf.eth0.disable_ipv6 = 1

I know there are still people sticking their head in the sand about ipv6, and in many cases a way to forcibly disable ipv6 is still a requirement.

set system ipv6 disable can be used to globally disable IPv6 address assignment
