It’s a valid concern IMO. Any application on X11 can install a key logger, record your screen, and influence other applications in a myriad of ways. With open source software from a trusted repository, this is not an issue, but an increasing number of people run random binary blobs from Steam, the Snap Store and Flathub. I am 100% certain that some less-conscientious publishers are already using X11 features to build ad profiles of their users; it’s a matter of time before the first ransomware will appear. The only sensible way to prevent this, is to confine applications to their own space.

But ok, more security isn’t a bad thing. But why not make it an option, like SELinux for example? That way users can choose a degree on a scale between security and convenience that suits their use case and circumstances. Why make it all or nothing?

Wayland simply doesn’t have protocols for most of this stuff. (Applications are supposed to use D-Bus and portals.) Developing new protocols that offer X11-like functionality is a large investment and will also need changes in the toolkits and apps to make it work.
