Tree2 is a complex component, so there might be open issues in some usecases.

Ah, tree2 got lucky! ;-) Then it's perhaps the right time to either make it more robust (my preference, tree2 is used a lot and is a very cool component - when it works) or move it to Sandbox because of all current issues. Meanwhile, perhaps people now of robust tree components with similar features?
