For Kubernetes 1.27, we intend to make some breaking API changes: - rename PodScheduling -> PodSchedulingHints (https://github.com/kubernetes/kubernetes/issues/114283) - extend ResourceClaimStatus (https://github.com/kubernetes/enhancements/pull/3802) We need to switch from v1alpha1 to v1alpha2 for that.
