Maybe more don't come out in favor because we get attacked when we do. What was proved in that thread about the renders was that there is a bug in the way firefly handles textures that aren't an even power of two, ie 256x256, 512x512, 1024x1024, etc. That should be fixed in the next patch due in about a week. There certainly could be more than a few that have no problems. We just aren't as vocal as those that do.
