There is no such thing as a tree view in QtQuick or QtQuick controls at the 
moment, but neither does QML depend on QtQuick nor has QtQuick.Conrols be 
feature frozen.

Even if we assume that QtQuick is to be used as the QML component technology, 
anyone could implement a tree view or column view either as a separate module 
or for upstreaming into QtQuick or QtQuick.Controls themselves.
