Following your advise, open_dataset can now open zarr files. This is done: python ds = xarray.open_dataset(store, engine="zarr", chunks="auto")

NOTE: xr.open_dataset has chunks=None by default, whereas it used to be chunks="auto" on xarray.open_zarr.

Additional feature: As a result of these changes, open_mfdataset can now (automatically) open multiple zarr files (e.g. in parallel) when given a glob. This is, python paths='directory_name/*/subdirectory_name/*' ds = xarray.open_mfdataset(paths, enginne="zarr", chunks="auto", concat_dim="time", combine="nested") does yield the desired behavior.

This is different from fsspec.open_local vs fsspec.mapper on intake-xarray when opening files with a glob. But agreed, that can be addressed in a different PR.
