The Xfce Wayland road-map on the project’s Wiki has been updated a few times over the past two weeks, namely around the desktop panel plug-ins and applications support for Wayland. There still isn’t a firm timeline or release where they expect to have a complete Xfce Wayland transition complete, but ultimately are aiming to have a native Wayland experience that doesn’t depend at all on XWayland and will be using wlroots as part of its compositor. Many Xfce panel plug-ins are working under Wayland as are a number of Xfce’s own applications.
Awesome, I knew XFCE had plans but I didn't expect them to work out that fast till somewhat recently!
