There was a design issue that we were re-entering xarray at the API layer. For example on posix and cloud we called open_dataset API again rather than handing off to the detected engine's BackendEntrypoint. And as a result, decoder resolution, cache wrapping and index creation therefore ran twice, once with the user's values on the outside, once with defaults on the inside. Wherever the inner default won, the user's argument was silently discarded. This PR is going to fix this issue.
