I don't see how Wayland would improve security in my case. There are basically two types of applications on my system: some which can't be used in sandboxes in a reasonable way and those which work well in sandboxes. In the first case I wouldn't gain anything with Wayland because my shellrc, launcher configuration, ssh keys, personal data, ... are accessible to those applications, giving them and a potential attacker basically full access to my system, including the control of all Wayland clients. In the second case, those applications work well with X security extensions and X11 proxies so I'm pretty fine in that regard, even with X11. And since X11 also works just so much better in the majority of cases I care about, regarding my productivity and flexibility, I don't see any reason to use Wayland right now.
