Is your feature request related to a problem?

Here are two datasets, in one a is a data_var, in the other a is a coordinate variable. The following fails ``` python import xarray as xr

ds1 = xr.Dataset({"a": ('x', [1, 2, 3])}) ds2 = ds1.set_coords("a") ds2.update(ds1) with 649 ambiguous_coords = coord_names.intersection(noncoord_names) 650 if ambiguous_coords: --> 651 raise MergeError( 652 "unable to determine if these variables should be " 653 f"coordinates or not in the merged result: {ambiguous_coords}" 654 ) 656 attrs = merge_attrs( 657 [var.attrs for var in coerced if isinstance(var, (Dataset, DataArray))], 658 combine_attrs, 659 ) 661 return _MergeResult(variables, coord_names, dims, out_indexes, attrs)

MergeError: unable to determine if these variables should be coordinates or not in the merged result: {'a'} ```

Describe the solution you'd like

I think we should replace this error with a warning and arbitrarily choose to either convert a to a coordinate variable or a data variable.

Describe alternatives you've considered

What happened?

python ds = xr.Dataset( {"a": ("x", [1, 2, 3])}, coords={"c": ("x", [1, 2, 3]), "d": ("y", [1, 2, 3, 4])} ) print(ds.coords) mapped = ds.map(lambda x: x) print(mapped.coords)

Variables d gets dropped in the map call. It does not share any dimensions with any of the data variables. Coordinates: c (x) int64 1 2 3 d (y) int64 1 2 3 4 Coordinates: c (x) int64 1 2 3
