From what's been said in the forums and implied in that email they sent to API users, they're leaving the functionality in and just no longer creating the folder on install.
My question is: How long is that functionality going to stick around for legacy users after it's been hidden by default?

For whatever reason, they seem intent on killing the feature. Extremely disappointing.
