[lxc-users] LXD with ZFS and limiting block I/O resources

As I understand ZFS is recommended filesystem for LXD. However is that
possible that limiting block I/O resources on ZFS is not working?

# lxc info | grep zfs
  storage: zfs
  storage.zfs_pool_name: lxd

# lxc config device set c1 root limits.read 10MB
error: Block device doesn't support quotas: 10:55

I'm aware of compatibility issues with ZFS io throttling via cgroup:

Am I missing something or limiting block I/O resources is really
currently impossible?
