My gut feeling is that esp for command line applications, a call equivalent to

$ xwininfo -d $DISPLAY -root

will be a better solution than creating a QApplication (rather than a QCoreApplication) to query the root window ID.

Alternatively, use Xlib APIs.

If there’s really no other way than adding something like QScreen::rootWindowId()  to Qt, then we can evaluate that, but it’s a niche problem that didn’t justify that we keep the outdated QDesktopWidget, or concepts that don’t translate well to other platforms around for now.
