A "security" that interrupts the user or prevents them from doing their work is bad, because it incentivizes the user to skip or disable it, and the use of a Linux system already can get most of the ways to do either of those via ${packagemanager} install. Thus it's more like security theatre.

From what I gather, the wayland model of things is so ridiculous that it can't even provide for global hotkeys - which are, like, the guaranteed way to setup an interface the user can trust because it'll always mean that when the user users it. I doubt wayland would even be Magic SysRq keys-compatible.
