Mapped normals are not always required. The r1 renderer offered variants of shaders that have mapped and vertex normals. It did this because it wasn't clear if using ubiquitous mapped normals would be too expensive in terms of performance. It turned out that it wasn't, so r2 used them everywhere and didn't provide any other kind of shader. However, mapped normals imply that meshes will have per-vertex tangents, and this may be unreasonable when meshes are generated at run-time.
