Sorry, I got a bit criss-crossed between this PR and the thread in #3470. 

In light of https://github.com/pydata/xarray/issues/3470#issuecomment-566214653 it seems like the next best thing would be  to given `assign_coords`  the optional ability to update the `DataArray`/`DataSet` in-place. Thoughts? ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,582708100

This change blocks the ability to update coordinate values in-place. This breaks code in a more fundamental way than just requiring users to rely on `assign_coords` - it can necessitate a substantial change in code design for people who were relying on the ability to mutate coordinates. This also leads me to ask: was it really appropriate to call such a substantial breaking change only a patch? ,"{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,582708100
