Its been stated many times that Jolla will _not_ be doing XWayland support and if someone wants it (cripled user experience with crappy X11 UI) then community needs to do the needed integration themselves.

Lipstick and wayland are OSS projects (https://github.com/nemomobile/lipstick) feel free to make pull requests there.

Personally I never want to see X11 apps in a phone, let those crappy UI apps remain in desktop only env.
