ServiceSubnet has to be limited in size, due to implementation details, and the mask can not allocate more than 20 bits. PodSubnet validates against the corresponding cluster "--node-cidr-mask-size" of the kube-controller-manager, it fail if the values are not compatible. kubeadm no longer sets the node-mask automatically on IPv6 deployments, you must check that your IPv6 service subnet mask is compatible with the default node mask /64 or set it accordenly. Previously, for IPv6, if the podSubnet had a mask lower than /112, kubeadm calculated a node-mask to be multiple of eight and splitting the available bits to maximise the number used for nodes.

But because the normal provisioning process is used (`PersistentVolumeClaim`), storage can be provided by third-party storage vendors and all of the usual volume features work. Volumes don't need to be empt; for example, restoring from snapshot is supported.

It changes the dual-stack API wrt Service from a single ipFamily field to 3 fields: ipFamilyPolicy (SingleStack, PreferDualStack, RequireDualStack), ipFamilies (a list of families assigned), and clusterIPs (inclusive of clusterIP).  Most users do not need to set anything at all, defaulting will handle it for them.  Services are single-stack unless the user asks for dual-stack.
