This kinda sounds on par with "A small debuff for any character that doesn't eat at least 1 piece of food item each in-game day". In some games, I am for such mechanics, but I don't see hunger or nightsight debuffs panning out anymore.
Personally, I keep darker nights toggled on in graphics options. It's annoying when it kicks-in inside a dungeon during a battle but I guess I'm a masochist for actively shafting myself with "realistic" gameplay mechanics like that.
However, when I can cast In Lor in less than 0.5s into infinity with infinite non-existent reagents... well, I guess we've kinda lost all perspective on reasonable gameplay mechanics anyway.
