 ### Risks and Mitigations
 
 The risks of adding this new feature are quite low.
-It is isolated to a specific policy option within the `CPUManager`, and is protected both by the option itself, as well as the `CPUManagerPolicyExperimentalOptions` feature gate (which is disabled by default).

 - [X] Feature gate (also fill in values in `kep.yaml`)
-  - Feature gate name: `CPUManagerPolicyExperimentalOptions`
+  - Feature gate name: `CPUManagerPolicyAlphaOptions`
   - Components depending on the feature gate: `kubelet`

 ###### Does enabling the feature change any default behavior?
 
 No. In order to trigger any of the new logic, three things have to be true:
-1. The `CPUManagerPolicyExperimentalOptions` feature gate must be enabled
+1. The `CPUManagerPolicyAlphaOptions` feature gate must be enabled
 1. The `static` `CPUManager` policy must be selected
 1. The new `distribute-cpus-across-numa` policy option must be selected
 
 ###### Can the feature be disabled once it has been enabled (i.e. can we roll back the enablement)?
 
 Yes, the feature can be disabled by either:
-1. Disabling the `CPUManagerPolicyExperimentalOptions` feature gate
+1. Disabling the `CPUManagerPolicyAlphaOptions` feature gate
 1. Switching the `CPUManager` policy to `none`
 1. Removing `distribute-cpus-across-numa` from the list of `CPUManager` policy options
