It's a similar kind of bread as gsl::owner<T> [1], which can help static 
analyzers to make correct assumptions about memory usage [2].

Just that I am not sure, if this very type really helps tools like 
clang-tidy to reduce false positives about memory leaks.

In my experience one currently cannot use truly useful clang-tidy checks 
like cplusplus.NewDeleteLeaks [3] with Qt code as clang-tidy tends to 
report a huge amount of false leaks with Qt code.

I do no know enough to judge, if parent_ptr<T> is the solution we want 
to use, but it would be really nice if one could use checks like 
cplusplus.NewDeleteLeaks with Qt.

Ciao
Mathias
