Same here. I think Daniel is on to something and we really should explore 
having smart pointers in Qt 6, but at this point I'm not convinced 
std::unique_ptr alone is it. I'd like to see what we could achieve with a 
QObject-specific smart pointer that understood ownership-taking functions 
(setParent, addWidget, etc.) and observing-only API (like connect()).
