Especially when this is such a high profile attraction and the only new ride for that area. The difference between this and Cedar Point is that a lot of CP rides are for a particular audience (people who love hardcore thrill rides). Cedar Point is known nationally for having one of the largest (if not The Largest) collection of really intense rollercoasters in the world. Most people, even larger sized rollercoaster enthusiasts, know that there is some trade off between having something be bigger, faster, and more intense and having it be more universally accommodating for riders. It's an unfortunate reality, but one that's pretty easy to grasp. Cedar Point wants to maintain its status as the rollercoaster capital, and so it's going to keep putting out more rides that are more and more restrictive. Fair enough, especially since the intensity of their rides rule out a large segment of the population that do meet their size, height and health restrictions. It's just the nature of that genre.
The Harry Potter fandom, however, attracts people of all heights, BMIs, ages, states of health, and tolerance for thrill rides. One would think that if you were to only to create one new ride for a land you want to appeal to fans of with as wide of a range of backgrounds and profiles as possible. Obviously, just about any ride they create is going to have some sort of restriction, but to make it so narrow excludes an unusually large section of their target audience. That's not smart business, especially when it's possible to create a good ride without relying on technology that would force so many restrictions into place. It's really hard to honestly market the WWoHP at families when the one original ride could end up excluding half or more of the family. Again, I think I'd feel differently if this ride wasn't their show piece or if they were building another rollercoaster, but that's not what this is.
I don't think the creators went out of their way to exclude anyone obviously, but I think it shows poor design when these sort of factors are not considered early in the design phase.
