Another quick comment, if we use fsspec rather than pooch, I think it's more likely that it is already installed as it should be a dependency of dask. See: https://github.com/xarray-contrib/cf-xarray/issues/422#issuecomment-1423034942

@dcherian Thanks for the heads up!

I think its OK. Xarray uses pooch for its tutorial datasets anyway...
