I don't really see my vast underground base being swamped by creepers and all as a good compromise here. That would be just as bad as the black fog.
1.7.x was just fine as it was in regards to these issues and no one was complaining about not having a black fog or monsters not spawning in lit up areas. I just don't see any reason to making it worse in any direction.
I think it's quite possible to reach a compromise, actually.
The best compromise I can think of would to be to allow the black fog to exist where it's already dark (as even without light you can still see alright in the darkness), but to vanish in the presence of light. That would be the most realistic way to handle it, actually; when you go into a dark cave in reality, it gets darker the deeper you go, unless you have light.
