Went to a show in Nashville with some friends, I think last year. And drones were definitely incorporated in (interestingly showing Star Wars and then US military assets), but it was done in tandem with the fireworks. Which as a distraction during transitional elements does seem like a good use for them.
Honestly I think the biggest threat is also fireworks NIMBYism, people don't like the loud sounds disturbing their lives, their pets, etc combined with the general pressure of bigger and better exacerbating those problems.
