860180906,MDU6SXNzdWU4NjAxODA5MDY=,5175,Feature to retrieve the underlying store,11022336,closed,0,,,6,2021-04-16T21:23:55Z,2023-09-16T10:19:19Z,2023-09-16T10:19:18Z,NONE,,,,"<!-- Please do a quick search of existing issues to make sure that this has not been asked before. -->

**Is your feature request related to a problem? Please describe.**
It would be useful if I could retrieve the underlying store from an xarray Dataset object. There was previously a workaround that allowed this, but that was [recently removed](a/xarray/pull/4809). 

```python
dataset._file_obj.ds  # Doesn't work anymore :(
```

**Describe the solution you'd like**
Ideally I'd like the API to be extended so the underlying store can be retrieved. Something like:

```python
>>> dataset = xr.open_dataset('/path/to/file.nc')
>>> nc_dataset = dataset.store
>>> type(nc_dataset)
<class 'netCDF4._netCDF4.Dataset'>
```

**Describe alternatives you've considered**
I'd be fine using the old workaround if that was still an option. If anyone knows of a different workaround I would be fine with that, but a better long-term solution would be an actual user-facing function for accessing the store.

I might be using the 'store' terminology incorrectly, but hopefully my request is clear with the above example.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/5175/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed,13221727,issue
