Is what you did *really* equivalent to bypassing the reflection in 
radiance samples ?

There is one thing I'm absolutely sure of : LightScape, which renderings
are found great by most everyone, *doesn't* account reflection for it's
radiance solution calculation.  In fact, due to it's algorithm, it 
*can't* !  Energy transfers can't take specular reflection into account.
Also, please note it doesn't even take *textures* in account (for the
same reason), only a plain diffuse color.  Finally, it doesn't render
bumps, but that's another issue.

As far as I could gather information, other radiance engines, 
monte-carlo/bidirectional/photons/... based, also *don't* take specular
reflection into account.
