Yes, the old behaviour was deemed harmful and removed. It was originally
an artifact of the implementation, but as it mirrored the behaviour of
the ReparentWindow request, it seemed like a reasonably good thing to
do. Experience with window managers and other applications proved
differently and the code was fixed to suppress these events.
