- Currently, DataArray does not have a `.variables` attributes.
- The state of a DataArray is stored in the form of variables in  `._variable` (an `xarray.Variable`) and `._coords` (of type `OrderedDict[Any, xarray.Variable]`).
- From a user facing API, you can get access to these variables via `.variable` and `.coords.variables` (I don't know if the later is clearly documented, but if not it should be).

So the ""infinite tree of DataArrrays"" only applies if you are accessing them directly via `.coords`, and under the covers data is represented in a pretty sane way.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,193294729

I agree that doesn't always make sense -- sometime coordinates really only describe the data variable(s), so keeping them around on coordinates merely because they contain the appropriate dimensions is inappropriate.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,193294729
