1775657305,I_kwDOAMm_X85p1mFZ,7945,engine='cfgrib' no longer an option in xr.open_dataset() but works anyway,74011857,closed,0,,,4,2023-06-26T21:32:01Z,2023-06-27T00:06:27Z,2023-06-26T21:37:05Z,NONE,,,,"### What is your issue?

Looking at the documentation for [xr.open_dataset()](https://docs.xarray.dev/en/stable/generated/xarray.open_dataset.html), the ""engine"" argument to that function is listed as accepting one of 7 different engines (or None), but the ""cfgrib"" engine is not among them. Looking at older versions of the documentation, I see that ""cfgrib"" was delisted starting with v2023.04.0 (it's still present in [v2023.03.0](https://docs.xarray.dev/en/v2023.03.0/generated/xarray.open_dataset.html)). 

In what I think is a related issue, [this tutorial](https://docs.xarray.dev/en/stable/examples/ERA5-GRIB-example.html) on reading in ERA5 GRIB files with the ""engine='cfgrib'"" option on xr.load_dataset() gives a ValueError in documentation versions starting with [v2023.04.0](https://docs.xarray.dev/en/v2023.04.0/examples/ERA5-GRIB-example.html) and going through [v2023.05.0](https://docs.xarray.dev/en/v2023.05.0/examples/ERA5-GRIB-example.html) and ['stable'](https://docs.xarray.dev/en/stable/examples/ERA5-GRIB-example.html) due to the unrecognized engine 'cfgrib', although it seems to have been fixed for [v2023.06.0](https://docs.xarray.dev/en/v2023.06.0/examples/ERA5-GRIB-example.html) and ['latest'](https://docs.xarray.dev/en/latest/examples/ERA5-GRIB-example.html). 

Given both of the above, I was surprised to find that using xr.open_dataset() on a GRIB file with engine='cfgrib' does work for me using xarray v2023.05.0. To me it seems that the documentation for xr.open_dataset() should be edited to include the 'cfgrib' option again, but I'd like to get an opinion from someone more familiar with xarray.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/7945/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed,13221727,issue
