Looks like you need to define a open_dataset_parameters class variable if you want to pass on kwargs. I would prefer this but I don't have much experience with the backends, so others opinions may differ @aurghs @alexamici

See for example:

https://github.com/pydata/xarray/blob/8c5c230881d616af32c5a42cca261eb11fce3916/xarray/backends/pseudonetcdf_.py#L107-L111

If you want to keep the named arguments I would probably avoid inspect and just pass kwargs that are not None:

```python kwargs = {"a": 5, "b": None}

only pass on kwargs that are not None -> pydap has some defaults that are not None

kwargs = {key: value for key, value in kwargs.items() if value is not None} ```
