It's almost as if there's a spectrum of filmmaking!
That said, The Walking Dead is particularly gruesome and visually unpleasant in a way that Hitchcock isn't/wasn't. Furthermore, great care has been taken to embellish the placemaking of that area... introducing Walking Dead would probably create a real clash.
Unless, of course, they moved the entrance over to Hollywood (next to Brown Derby), freeing up a decades-long roadblock and shifting more foot traffic to the right...
