Attempts to enable/disable individual resources in other API groups will print a warning, and will return an error in future releases. ([#72249](https://github.com...

DOS vulnerabilities for `CVE-2023-44487` and `CVE-2023-39325` for the API server when the client is unauthenticated. The mitigation may be disabled by setting the `UnauthenticatedHTTP2DOSMitigation` feature gate to `false` (it is enabled by default). An API server fronted by an L7 load balancer that already mitigates these http/2 attacks may choose to disable the kube-apiserver mitigation to avoid disrupting load balancer -> kube-apiserver connections if http/2 requests from multiple clients share...

  The feature gate `DisableKubeletCloudCredentialProviders` is currently in Alpha, which means is currently disabled by default.
