See #8288

  • [ ] Closes #xxxx
  • [ ] Tests added
  • [ ] User visible changes (including notable bug fixes) are documented in whats-new.rst
  • [ ] New functions/methods are listed in api.rst

These changes allow me to make a pretty minimal subclass that just swaps out the netCDF4.Dataset class for my version:

```python from xarray.backends.netCDF4_ import NetCDF4BackendEntrypoint, NetCDF4DataStore from ._wrapper import Dataset # This is my netCDF extension

class NcComplexDataStore(NetCDF4DataStore): @classmethod def DatasetClass(self) -> type: return Dataset

class NcComplexBackendEntrypoint(NetCDF4BackendEntrypoint): DataStore = NcComplexDataStore ```
