 A default VolumeAttributesClass can be specified for the Kubernetes cluster. This default VolumeAttributesClass is then used to dynamically provision storage for PersistentVolumeClaims that do not require any specific VolumeAttributesClass. A cluster admin can use annotation to manage default VolumeAttributesClass. The default VolumeAttributesClass has an annotation volumeattributesclass.kubernetes.io/is-default-class set to true. Any other value or absence of the annotation is interpreted as false. 
 
+Note: For Kubernetes versions ≤ v1.31, the VolumeAttributesClass feature does not support a default VolumeAttributesClass. This is because there is already a natural default for VolumeAttributesClass: no VolumeAttributesClass associated with the PersistentVolumeClaim. Furthermore, with a default, there would be added overhead for cluster operators in making sure a cluster's default StorageClass and default VolumeAttributesClass are compatible. Use-cases and support for Default VolumeAttributesClass will be re-evaluated during this feature's beta in Kubernetes v1.31.
+
 #### Pre-provisioned Volume
 
 The cluster admin has created a group of PVs with VolumeAttributesClass and an end user is binding PVCs to pre-provisioned PVs. The PVCs will honor the VolumeAttributesClass. It is up to the cluster admin to make sure the parameters in the PVs matching the parameters in the VolumeAttributesClass. This behavior is similar to StorageClass.

+Note: These Administrator Quota Restrictions are not available for Kubernetes versions ≤ v1.31, due to a [bug](https://github.com/kubernetes/kubernetes/issues/124436) in the implementation of the `scopeSelector` feature. Because there is no default quota, we will be able to add quota support in a future version of Kubernetes without breaking existing workloads.

 ### Notes/Constraints/Caveats (Optional)
 
 The parameters in VolumeAttributesClass are opaque and immutable. This gives different cloud providers flexibility but at the same time it is up to the specific driver to verify the values set in the parameters. The parameters from VolumeAttributesClass associated with a volume are mutable because they are coming from different VolumeAttributesClasses.

+
+Prior to this enhancement, we loop through all PVCs, check if `pvc.Status.Phase == v1.VolumeBound` and increment the relevant metric only on `namespace` dimension. When the feature flag is enabled, new metrics will take into account `namespace`, `storage_class`, and `volume_attribute_class`. 
 
-Prior to this enhancement, we loop through all PersistentVolume objects, check if `pv.Status.Phase == v1.VolumeBound` and increment the appropriate `pv.Spec.StorageClassName` bucket. For these new metrics, when the feature flag is enabled, we also increment the appropriate `pv.Spec.VolumeAttributeClassName` if it is not empty. 
+With these additional labels, cluster operators can alarm on these new metrics to detect PVCs that are not able to bind. With the additional StorageClass and VolumeAttributesClass name labels, cluster operators can more easily check whether VolumeAttributeClass or StorageClass object misconfiguration is the cause of these binding issues.
