This is an attraction that kids can actually go on as long as they can stand up and it also is wheelchair friendly. The only other rides in the park that have no height requirement are K&K and Hogwarts Express (and I don't exactly think of that as a ride as much as a mode of transport). Aside from shows like Animal Actors, Bourne, and Horror Makeup after that, there's not a lot to do for extremely young kids which many families are disappointed by when they visit. Most kids can probably do ET and Fallon as well, but that's really it in the park.
So to answer your question, yes, this was needed.
