Usage stats of CephFS subvolumes

Is there a way to gather and show the disk usage stats of CephFS subvolumes?

Is there anything similar to rbd du for CephFS subvolumes?

The only idea I have is something really ugly:

filesystem="ceph-filesystem"
group_name="csi"
for subvolume in $(ceph fs subvolume ls "${filesystem}" --group-name "${group_name}" | jq -cr '.[].name?'); do
    subvolume_info=$(ceph fs subvolume info "${filesystem}" "${subvolume}" "${group_name}")
    bytes_quota="$(echo "${subvolume_info}" | jq '.bytes_quota')"
    bytes_used=$(echo "${subvolume_info}" | jq '.bytes_used')
    echo "${subvolume} ${bytes_quota} ${bytes_used}"
done

I believe, there should be something more elegant.

Thanks in advance.
