Somehow this does work properly for modifying coordinates on `Dataset` objects, though:
```
In [9]: ds = arr.to_dataset(name='foo')
In [10]: ds
Out[10]:
Dimensions: (abc: 3)
Coordinates:
* abc (abc) int64 0 1 2
Data variables:
foo (abc) int64 0 1 2
In [11]: ds['abc'] = new_coord
In [12]: ds
Out[12]:
Dimensions: (abc: 3)
Coordinates:
* abc (abc) int64 1 2 3
Data variables:
foo (abc) int64 0 1 2
```
The logic here is mostly in here: https://github.com/pydata/xarray/blob/v0.7.0/xarray/core/merge.py
There's clearly something missing in the DataArray path (which goes through merge_dataarray_coords)... possibly we need to be using the overwrite_vars argument?
