Documentation of QML elements does not show the complete inheritance

C++ types in Qt docs show all the subclasses. For instance for QObject https://doc.qt.io/qt-6/qobject.html there's 280 subclassed listed.

But this is not the case for QML elements; for instance QtObject https://doc.qt.io/qt-6/qml-qtqml-qtobject.html does not show any subclasses. The subclasses instead show that their parent is QtObject, like https://doc.qt.io/qt-6/qml-qtquick-item.html . However that page does not show ALL the Item subclasses.

(It seems that there's a "modularization" in the QML docs that is not present in the C++ ones. Elements from different modules are not linked together.)
