Any mechanism that allows you to listen to hotkeys at will is about as insecure as running a program as root that snoops keys; either way you're vulnerable to keyloggers. The X implementation is quite insecure as well as having a number of other usability issues. I understand your complaints about Wayland but there has just never been any API for this that I've seen on any Linux window system that is actually secure, it just doesn't exist right now. If a secure API is ever implemented, it will probably be made to work with Wayland somehow.
