I see - thanks a lot for the quick response. I knew there was a good reason for this.

I wonder if it is reasonable to return a scalar when there is neither coords nor attrs associated with the return value, or it would be too much ad-hoc thing. For example, in the original example the return value was <xarray.DataArray ()>, which does not have any useful information.

I think this might be reasonable because I only get into this issue when I'm doing an array-wide operation and I know I'm going to get an aggregate scalar and forget to use .values.
