additional to forman's comments I would like to note that for the xarray rolling operation a stride would be useful in some use-cases. I have understood, that no work is currently planned, but wanted to leave this remark for further contributions. 

I.e. 

```
DataArray.rolling(min_periods=None, center=False, **windows)
```

with 

```
windows={dimname: (size, stride=1)}
```

Thanks for xarray! It's great!
