It should not be possible to create coordinates with inconsistent dimension sizes.

I would hesitate to drop coordinates associated with core dimensions that appear in both the input and output, because there are definitely functions that *do* preserve dimension identity, e.g., for a ufunc that normalizes across a dimension, e.g., `centered_in_time = xr.apply_ufunc(lambda x: x - x.mean(axis=-1), ds, input_core_dims=[['time']], output_core_dims=[['time']])`.

I think your ""Case 2: Specifying a new output dimension name"" should be the recommended pattern here. This already removes all coordinates associated with the input core dimensions (since they are not specified on outputs), so you can simply rename the output dimensions to achieve your desired result, e.g., `dr_out2.rename({'x_new': 'x'})`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,298834332

Based on your example, I think we should be raising an error when constructing the output object. That won't help your use case which we do want to support so I think another option to drop the coordinate may also be in order.
