So I wonder if introducing this as a "transition" to full UI scaling has any real value. Say this breaks fonts in some apps, then we land full UI scaling - will those fonts break again?

I don't think so. QPlatformSCreen::pixelDensity() is orthogonal to that. As I said, logicalDPI() is a conversion from point size to pixel (probably device independent ones). Those scaling factors act at pixel level, after the conversion from point size has been done.

That said, tested multiple values of QPlatformScreen::pixelDensity() and it had not impact whatsoever on QWidget apps (with or without this logicalDpi) patch. devicePixelRatio() seriously brake QWidget-based apps with or without this logicalDpi patch.
