When working with wind vector data, it is important to know if the vectors represented are grid- or earth-relative vectors. To get this information, a user currently needs to explicitly read this GRIB key.
import xarray as xr
xr.open_dataset(
"/path/to/file.grib2",
engine="cfgrib",
backend_kwargs={"read_keys": ["uvRelativeToGrid"]},
)
Since this detail is necessary when interpreting wind vectors (i.e., comparing modeled wind to an observation), I suggest this GRIB key be included in the DataArray attrs by default.

Describe the solution you'd like
If I'm right, I think this key can be simply added in the list here https://github.com/ecmwf/cfgrib/blob/eacde4c3fbf2eae4fa0ca2b1070c0f77481c7045/cfgrib/dataset.py#L40-L48
