@MaximilianR Let me help clarify:

  • 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.
