Include _ARRAY_DIMENSIONS metadata?

Ref https://ngff.openmicroscopy.org/0.4/#image-layout

├── .zgroup               # Each image is a Zarr group, or a folder, of other groups and arrays.
├── .zattrs               # Group level attributes are stored in the .zattrs file and include
│                         # "multiscales" and "omero" (see below). In addition, the group level attributes
│                         # must also contain "_ARRAY_DIMENSIONS" if this group directly contains multi-scale arrays.

Should we include this additional information?

EDIT: ome/ome-zarr-py#166 (comment) says that

Closing for now, the requirement has been removed from the 0.4 specification. Various layout currently allow to use xarray together with OME Zarr datasets. Hopefully the discussion in ome/ngff#48 will converge towards a set of recommendations that can be reintroduced later allowing compatibillity.

Thus I guess this is a typo in the specs?
