  no, the Containment* instances are all created immediately, as well the contained ContainmentInterface*
  What's created on demand (that is heavy indeed) is the qml stuff, which is created when the ContainmentInterface* gets a view, which can be controlled by the qml part of the shell (ie, when to cann this function and reparent the resulting ContainmentInterface*)
