WindowsUi Project "Reunion"

Just reading that Microsoft announced to unite different API and UI in his Projekt “Reunion”
https://docs.microsoft.com/en-us/windows/apps/winui/winui3/

Everything still work in progress and we all know the difference between announced and shipped.
But are there any thoughts on this regarding Xojo?

I was only reading about xaml islands the other day, you can technically use this via the uwp xaml hosting api but you might as well throw any cross platform ability out the window.

As for Xojo implementing this, I think the same issues with cross platform would exist with massive visual/design differences between macOS and Fluent.

Overall, I’m not sure, I’ve not really sat and thought about it at great length.
