@benbovy I also just tested the get_unique() method that you mentioned and maybe noticed a related issue here, which I'm not sure is wanted / expected.

Taking the above dataset ds, accessing this function results in an error:

```python

ds.indexes.get_unique()

TypeError: unhashable type: 'MultiIndex' ```

However, for xindexes it works: ```python

ds.xindexes.get_unique()

[<xarray.core.indexes.PandasMultiIndex at 0x7f105bf1df20>] ```
