I'm re-pinging this issue since I was just bitten by it (on version 0.15).

If creating an exception is time consuming could we instead have a disclaimer regarding this behavior to the documentation? Here's a basic working example that shows that it does silently fail:

```

Basic working example of the silently failing indexing assignment

ds = xr.Dataset({'a': (('x'), np.arange(4)), 'b': (('x'), np.arange(4)) })

Silently fails assignment

ds.loc[{'x': 1}]['a'] = 10 print(ds)

Works as intended

ds['a'].loc[{'x': 1}] = 10 print(ds) ```
