Long term, do you think it would make sense to merge together Indexes, Coordinates and IndexedCoordinates? They are sort of all containers for the same thing.

Yes I think so.

I'm actually trying to merge IndexedCoordinates with Coordinates but I'm stuck: the latter is abstract and I don't really see how I could refactor it together with DatasetCoordinates and DataArrayCoordinates. Do you have any idea on how best to proceed?

Ideally, I'd see Coordinates be exposed in Xarray's main namespace with at least the two following constructors:

```python class Coordinates:

def __init__(
    self,
    coords: Mapping[Any, Any] | None = None,
    indexes: Mapping[Any, Index] | None = None,
):
    # Similar to Dataset.__init__ but without the need
    # to merge coords and data vars...
    # Probably ok to allow more flexibility / less safety here?
    ...

@classmethod
from_pandas_multiindex(cls, index: pd.MultiIndex, dim: str):
    ...

```
