and auto translate to equivalent value map editor config or range config.
Requires GDAL 3.3+
For formats which support embedded definition of field domains (currently Geopackage and GDB), this change automatically converts the embedded field domain over to the equivalent QGIS editor configuration for the field.
Practically it means that GPKG/GDB with coded field domains will automatically load into QGIS with their correct Value Map widget configuration intact, so that users see immediately the nice descriptions for field values instead of the raw codes. If the field has a range type domain (i.e. a min/max value allowed in the dataset) this will also be translated to the range widget for the field.
