Mostly for consistency with `sel` & because there was no `drop_isel`. I don't have a strong opinion. I agree it's inconsistent - but it's also convenient and IMHO not surprising.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,787692043

> It would be great to do this for DataArray too — it can be a very simple wrapper of this method.

Just to add on to this - the wrapper can be written as:

```python

class DataArray:
    ...

    def drop_isel(self, indexers=None, **indexers_kwargs):
        """"""Drop index positions from this dataset.
        ...
        """"""
        dataset = self._to_temp_dataset()
        dataset = dataset.drop_isel(indexers=indexers, **indexers_kwargs)
        return self._from_temp_dataset(dataset)

    ...

```
