There is a concern that some GCE users may be running automation that (a) turns up ephemeral clusters and (b) always uses the latest K8s release. If any of these workloads fall outside the set supported on GCI, cutting the release will break the automation. We are therefore delaying this change until we have provided sufficient warning.
