That's probably the outcome from QTBUG-78445, which resulted in QTBUG-80792

There is work ongoing to *allow* separate Qt debug builds again, but the
official release will (most likely) only contain release DLLs with
separate debug information.

I'm actually doing the other way round, as I'm always shadow-building,
so the additional only complicate things.
