Ok, so ds.rolling.mean allows for min_periods while ds.rolling.construct.mean allows for fill_value?

On the other hand, using skipna=False resores the default behaviour or ds.rolling ``` ds.rolling(dim=3, center=True).construct('window').mean('window', skipna=False)

RESULT: array([nan, 1., 2., nan])

```

Actually I'm sure that min_periods and fill_value are not the only differences between the two - but that's how far my understanding got at the moment.
