Proven is a bit strong word. Shortcuts can work, accessibility can work etc. Integration with OS stuff depends on the API OS exposes. Only mimicking & integration lags behind and only after the updates that actually change platforms UX. There is nothing magic about the "feel" that can't be implemented. It is a lot more work to develop a quality framework like this though. On the plus side it can work on the platforms without desktop environment.
