The thing that bothers me most about root is that some parts of it are basically not maintained at all.

There are serious bugs in RooFit which haven't been fixed in years. Wouter Verkerke has abandoned it (from what I can tell). Lorenzo Moneta is fixing the worst potholes, but it seems is has no authority or no time to tackle the misguiding interface and the broken scaffolding of RooFit.

Maybe ROOT7 will be a chance to take ownership of RooFit again.
