I never understood why this argument over fog has to happen. A hedge is an object, blocks vision, and can plausibly emit arrows without straining plausibility. In fact, one of my biggest reasons for house-ruling away advantage on ranged attacks for being unseen is because actual, non-illusionary bushes were implausibly useful to archers. Now I only grant advantage to unseen melee attackers.
Object lesson: this squirrel hedge is an object that blocks vision but not arrows.
How plausible is it that a shrubbery instantaneously appears? Fog always made sense because it's an actual spell and objects can cause it too. But...a summoned shrubbery? Seems like a wall of stone with a small gap to fire through is more summonable in a dungeon setting than a shrubbery.
