Why? The golden BB theory is well established and works in practice. A lot of planes and helicopters have been shot down in wars by numbskulls blindly firing pistols and rifles into the air hoping for a lucky shot. Before surface to air missiles and other smart weapons came about standard air defense was to fill the sky with as much lead as possible so you'd be bound to hit something by accident. And since Tolkien did it in the Hobbit it's become part of dragon lore that a dragon can be brought down by a single shot that hits in the right place. And we know that the dragons are at least somewhat vulnerable to piercing weapons, they took a lot of damage from spears and arrows in Mereen.But Cersei has big crossbows now! eyeroll: That was the dumbest thing this season... possibly all seasons).
Ultimately, this is probably a case of Chekhov's Gun. If it wasn't going to be important later there would not have been a scene showing it now. So it's either going to be used to kill a dragon or re-purposed to do something else that is critical to the story.
