I mean, isn't TWDA's more "Advanced" in the means that they achieved the fake-fire effect, as compared to Trick R Treat's? If I recall, TWDA uses Faux-fire, similar to what you see from the final big scene of Revenge of The Mummy at Orlando and Singapore.
That said, Murdy working with Peele directly, does make more hope come in; as it'll ensure an area of quality for the maze.
