I doubt they prioritized it. To get normal maps you usually first need a high resolution mesh, but then need other steps to get good decimation for lods and normal bake. That's mostly extra work, not alternative work that wasn't prioritized. If by transparency they mean faking aggregates, you also need full geo there before sampling and baking down into planes or some other impostor technique.
