- Added new k8s.io/component-helpers repository providing shared helper code for (core) components. ([#92507](https://github.com/kubernetes/kubernetes/pull/92507), [@ingvagabund](https://github.com/ingvagabund)) [SIG Apps, Node, Release and Scheduling]

### SIG Scheduling

- Finished initial generic controlplane refactor of kube-apiserver, providing a sample binary building a Kubernetes-like control plane, but without container orchestration resources.
