Then Windows 10 apparently lacks a native GUI toolkit, because it's certainly not "designed for" just one.

A similar thing happened to Android.

Windows 10 has several native GUI toolkits. The same thing happened in MacOS, which transitioned from Carbon to Cocoa.

If the widgets are drawn by a toolkit that isn't bundled with the OS, it's a non-native GUI. Of course, this isn't always a bad move.

One could argue Win32 is still the de-facto GUI toolkit in Win10. Things like .NET Windows Forms and (non-WinUI3) UWP are actually rendered with Win32 common controls.

WIN32 isn't de facto it is the canonical API for Windows. It always has been, since like the 1980's.

Indeed, but with some exceptions. .NET SWF shipped with extremely kludgy drawn clones of toolbars and menu bars instead of using the native ones (although the native ones were later exposed) and the result is that those particular controls on SWF apps did not age gracefully (DPI problems, system theme mismatch, scroll acceleration issues, etc). That’s the kind of thing Qt would also face with drawn components skinned to look like the real deal.
