[Development] Usage of final keyword in Qt6

[Christian Ehrlicher]

Hi,

while discussing QTBUG-89423 /
https://codereview.qt-project.org/c/qt/qtbase/+/326658 the question
about the final keywords arised - I know that I once wanted to use it in
Qt5 and it was not allowed back then. Are there any reasons to not use
final for internal classes/functions in Qt6?


Thx,
Christian
