We have a new "sparse=True" option in xarray.Dataset.from_dataframe for exactly this use case. Pandas's to_xarray() method just calls this method, so it would make sense to forward keyword arguments, too.

Would it be possible that pd.{Series, DataFrame}.to_xarray() automatically creates a sparse dataarray - or we have a flag in to_xarray which allows controlling for this. I have a very sparse dataframe and everytime I try to convert it to xarray I blow out my memory. Keeping it sparse but logically as a DataArray would be fantastic
