> Back to the topic - in case we really want to support the "stack case", I’d say shared_ptr is the only option (in combination with enable_shared_from_this which is already a kinda part of QObject, as mentioned above)

QObject ownership isn't shared, it's unique. A widget is in ONE 
hierarchy, which fixes its owning native window, its coordinate system, 
its Z order amongst its siblings; not N hierarchies.
