output_dtypes: yes I think the docs should be updated

What I was trying to say - this is a change that can break existing code and it is not easy to do a proper deprecation cycle (i.e. only throw a warning). (I think allow_rechunk=True is not a good default.)

Ok an easier idea (could be brittle, though):

```python try: res = da.apply_gufunc(...)

catch error that was not raised in earlier versions of xr.apply_ufunc

except ValueError as e: if "with different chunksize present" in str(e): warnings.warn(str(e) + " This will throw an error in the future.") res = da.apply_gufunc(..., allow_rechunk=True) else: raise

``` However, I am only throwing around ideas - this is certainly not up to me. Let's see what the others think. Maybe they have an opinion or a better idea.
