The ""infinite tree"" was causing some of the tests back at #1147 to do weird things (pytest seems not to handle infinite recursion responsibly).

When would / wouldn't it?

Currently, it may or may not. And its coords may or may not be DataArrays, which makes the tree of objects seemingly complicated (maybe it needs to be?). But it means we're special-casing some of the checks in https://github.com/pydata/xarray/pull/1147
