You can make level updates (at least with most games) as patches that you are forced to download as soon as you boot up the game. Problem is even a little level update is a big download, and multiple updates to the same level is about the same size so they should probably wait to find as many fixes as possibly. Also patches can get expensive so might as well wait even longer and do as much in one patch as possible.
I just hope something is done. Sure we could just make no-wingsuit events but I like the wingsuits, just not when they can "cheat" like that. And that doesn't even cover other level exploits that don't involve any special gear.
They would also have to reset all leaderboards involving every updated track. That's tricky.
