It's just that, when all you need to do is apply an elementwise, embarassingly parallel function (80% of the times in my real life experience), apply_ufunc is overkill.

The thing I have against the name map_blocks is that backends other than dask have no notion of blocks...","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,484752930

A few design opinions:

1. could we call it just ""map""? It makes sense as this thing would be very useful for non-dask based arrays too. Working routinely with scipy (chiefly with scipy.stats transforms), I tire a lot of writing very verbose ``xarray.apply_ufunc`` calls.

2. could we have it as a method of DataArray and Dataset, to allow for method chaining?

e.g.
```python
myarray.map(func1).chunk().map(func2).sum().compute()
