If you do this, then you'll need an explicit element to turn on / off
IPv4 or IPv6 addressing for the inteface as whole. ie to stop the
automatic addition of a link-local address.
By having the container, for each family, the prescense or not of the
container can define whether that address family is enabled for that
inteface.
