Strictly my opinion here. No stolen plans or high level deep throats. I don't think that they ever planned on removing all the curbs to begin with. You are talking about major changes to make that happen. What kind of changes you ask? Well, I'm so glad you did, cause here are the hardships involved with doing that. First you want to see a major increase of lost balance falls, runaway strollers, etc., well imagine that all the sidewalks down Main Street would be tilted toward the level of the road in order to avoid a step up to the retail locations. That would make main street look more like a bowl then a street.
There are only two ways to fix that unless one is able to completely change gravity and so on. That would mean that they either have to raise the street to the level of the present sidewalks (about 6 inches) or lower the buildings to the levels of the streets. Adding depth to the street would mean rebuilding or eliminating the trolly tracks and would also add substantial weight to the utiladors that are under it. Just for the sake of argument lowering the buildings to be level would require jacking up the buildings, removing 6 inches from each and every foundation and again creating havoc with utiladors and utility lines.
So the only thing that can actually help the main street situation is to enlarge the ramped sections for wheelchairs and disabled access and, just like that, you have a more efficient Main Street and something that I'd be willing to bet the farm on, is exactly what is happening. Strike that last sentence...it sounds way to much like gambling.
