So you say.

I suspect that unless you made the "gods of darkness" unattractive in other ways, people would still do it. Never count on a strongly utilitarian option being skipped because it has a bad look.
And if you did do that, people would simply still keep trying to find a way around it. Because the truth is, people for the most part find struggling with lighting conditions neither interesting nor fun. Carefully walling it off to only monsters just makes them more irritable about it, not still want to do it. Heck, if so many monsters didn't have it they'd likely be less prone to want it in the first place.
Without any intent to be dismissive, I've got to suggest you're probably playing the wrong game if you're playing D&D, then.
