Oh, no doubt. Part of the reason Slinky is so popular is the fact that a large % of attractions at DHS have higher height restrictions. Building a couple kid friendly attractions at DHS would help in certain areas. However:While I think your point is valid, a lot of people with younger kids need some spinner type attractions. A lot of the recent, "big" attractions all have height requirements. Galaxy's Edge needs at least one ride that doesn't have one. They don't all have to be as simplistic as Swirling Saucers, but those types of rides do serve a purpose.
- The impact on wait times for thrill rides will be negligible
- More rides means more guests and longer visits
I WANT disney to build as much as possible. If nothing else, their motivation should be to grow attendance. But I don't see an obvious path to the utopic short wait times that some suggest would result if Disney would simply build more.
