OSes that come with a native UI obviously have that as the default. But there will never be a default across OSes I think. Web UIs might be that, but I sure won't want to use html or js anywhere in my UI's if I can help it, even if cross platform. Java might perhaps be the best example of trying to make a default-for-a-language cross platform UI (Swing and whatever it was called that came before it). But I think it's also an example of why it might not be a great idea to even try. I think a key realization is that an app like Blender or AutoCad need a different UI paradigm than Spotify or a game overlay does, even on the same platform there are differences there. Apps that can use web based UIs tend to be more like Spotify than Blender...
