I'm wary of always keeping coordinates, because some applied operations could make existing coordinates no longer valid. For example, suppose you want to use pandas's faster time-resampling, i.e., `ds.apply(lambda x: x.to_pandas().resample('24H'))`. Any coordinates along the `time` would no longer be valid. We could automatically align the coordinates, but that starts to get increasingly magical...
