So now we've reached the point of "you could secure X11 if you changed everything". Sure, fine. Once again, for emphasis: nobody has stepped up to do that, in the history of X (outside of proprietary products, of unknown quality). Wayland is not some outsider project competing against X11. It's the people who were developing Xorg, saying they're fed up with X11 and need a clean slate to fix its problems. Here's my unpriviledged user trying to ptrace my Wayland compositor running as me: strace --syscall-limit=1 -p 697351 strace: attach: ptrace(PTRACE_SEIZE, 697351): Operation not permitted Nearby, I have a Chromebook where a potentially hostile virtual machine can display Wayland windows seamlessly on the host. The worst the VM can do is fill bitmaps with offensive imagery. In a world where the people doing the work switched to developing the Wayland ecosystem, arguing about a "could" that requires changing every window manager seems like a guarantee X11 will not get improved. Feel free to put effort into it...
