> where you want random software downloaded from the internet to be able to control the whole thing for e.g. screen recording, global hotkeys, window management mods, etc etc I don't want "random software" to be able to do those things. I want to grant these powers to a few select applications and not to everyone else. X11 has no intra-session security model. This lack of security doesn't make it better for desktop or form a case for maintaining X and Wayland in parallel. To the extent Wayland still has trouble with clients that want to manage windows, it's a matter of missing protocol extensions, not architectural flaws in Wayland that make it and X11 fundamentally suited for different use-cases. You've chosen a poor example if you're trying to use Wayland to show that we need different software stacks for different use cases. Cross-use-case software stacks are common, work well, and are fundamental parts of the computing universe.
