yes, spatial_ref is AFAIK a GDAL specific thing that predates the 
introduction of crs_wkt in the CF conventions (cf 
https://github.com/cf-convention/cf-conventions/issues/222, 
https://github.com/opendatacube/datacube-core/issues/837 where this is 
also discussed). Recent GDAL versions write both crs_wkt and spatial_ref 
as a transition step. This would complete the transition by removing 
writing spatial_ref (presumably we'd still accept it on the reading side 
for older datasets). Code that only checks for spatial_ref should be 
adapted to deal with crs_wkt, since it is the standardized attribute, 
independently on whether GDAL discontinues writing spatial_ref or not.
