It would be the WinRT platform plugins, which are located in:
Qt Base (the WinRT QPA plugin)
Qt Location (WinRT positioning backend)
Multimedia (WinRT backend)
Qt Sensors (WinRT backend)

I think we are able to use the existing LGPLv3 / GPLv2+ / commercial header template, so the change should be straightforward.
