The use of Diffuse to either capture "negative" reflected light, or to detect a difference between Diffuse with-and-without Normals_Forward does seem to work and I recalled that this is possibly a valid approach. However, it doesn't work with indirect light, and I ALWAYS use indirect light, so be careful with that.

Ah yes, there's always something, isn't there? Thanks for the heads up!
