Well, not specifically, but with NetworkManager we do have a "disable
IPv4" method for IPv4, which now just doesn't do any kind of IPv4, but
obviously doesn't disable IPv4 entirely because that's not possible.  I
was only thinking that it would be nice to actually guarantee that IPv4
was disabled, just like disable_ipv6 does.

But we could certainly implement that draft if a patch shows up or if it
bubbled up the priority stack :)
