The upstream bug I had opened,
https://bugreports.qt.io/browse/QTBUG-107459, has now been closed as
"Believed not to be a problem.", so it's indeed supposed to work.

I'll try looking into reverting some of the changes made when Qt 6 was
introduced; there may be warnings, if I recall correctly, but since it's
advertised as something supported, let's put it to the test!
