"This best practice is not meant to provide detailed guidelines on (a) which is the right level of accuracy and precision for different use cases, or (b) how to generate and publish alternative geometries for Spatial Things. "
But much of the 'possible approach' text does 'how to generate' alternative geometries, especially in item 3: generalisation, including reducing precision or reducing dimensions
