They have implemented this at all Disney Theme Parks and Resorts. To be honest, it works... as much as I kinda hate that they created a more cumbersome security detail and bag check, the system itself is actually more efficient. Think about it, if you get bag checked and they find something that isn't allowed in the park *cough* Selfi-Stick *cough* then you don't need to go on a long trek back to your car, it's simply a short walk instead. More than that though over here in CA, Downtown Disney is now within the bag checked zone, so you can freely go shopping in it's stores and back to the park without having to re-check the bags.
