This would help new users like https://github.com/pydata/xarray/issues/1113 and simplify the RTD build process (https://github.com/pydata/xarray/issues/1106).

The problem is that it is not as trivial as expected. On the latest master:

python import xarray as xr ds = xr.tutorial.load_dataset('rasm') ds.to_netcdf('rasm.nc', format='NETCDF3_CLASSIC', engine='scipy') Throws an error:

```python
