Well, this goes against not just what the parks were in the past but what they are now. If there is a park that looks to the past, maybe it's the one with comics and cartoons from the 1920s? Or a whole land about mythology? If anything USF should be the bleeding edge park with the most modern IPs and attractions while the other parks can support more timeless things.
Back in the 90s it was the Disney fans making fun of USF being too modern with Beetlejuice, ET, Ghostbusters, BTTF, and Nickelodeon. The park had "too many thrill rides" and "nothing worked". One of the strengths of Universal, for better or worse, is the fact that they will make those hard decisions to replace things. 30 years from now there will be people making your same post but instead "USF should go back to the classics like Jimmy Fallon, F&F, Simpsons, and Minions".
