When the kubelet volume stats metrics will be supported in csi-vxflexos?

Hi,
It seems that below metrics are not supported yet in current version of  csi-vxflexos, how about the plan to support them?

kubelet_volume_stats_capacity_bytes
kubelet_volume_stats_available_bytes
kubelet_volume_stats_used_bytes
kubelet_volume_stats_inodes
kubelet_volume_stats_inodes_free
kubelet_volume_stats_inodes_used
