RetroactiveDefaultStorageClass is beta in 1.26 

Changing feature state to beta and correcting the article by removing
reference to its feature gate. As this feature no longer opt-in this
article makes more sense without it.

#### Retroactive default StorageClass assignment
{{< feature-state for_k8s_version="v1.25" state="alpha" >}}
{{< feature-state for_k8s_version="v1.26" state="beta" >}}
You can create a PersistentVolumeClaim without specifying a `storageClassName` for the new PVC, and you can do so even when no default StorageClass exists in your cluster. In this case, the new PVC creates as you defined it, and the `storageClassName` of that PVC remains unset until default becomes available.
However, if you enable the [`RetroactiveDefaultStorageClass` feature gate](/docs/reference/command-line-tools-reference/feature-gates/) then Kubernetes behaves differently: existing PVCs without `storageClassName` update to use the new default StorageClass.
When a default StorageClass becomes available, the control plane identifies any existing PVCs without `storageClassName`. For the PVCs that either have an empty value for `storageClassName` or do not have this key, the control plane then updates those PVCs to set `storageClassName` to match the new default StorageClass. If you have an existing PVC where the `storageClassName` is `""`, and you configure a default StorageClass, then this PVC will not get updated.
