That's what Ctrl-Alt-Del is for. They aren't exactly the same thing, I suppose, but there's enough functional overlap that if you already have one, it's hard to justify adding another. You don't want too many of these "escape sequences", because every kernel-side keyboard interrupt becomes a thing that: * Userland doesn't get to use that keyboard shortcut any more. * Someone might accidentally trigger, and if they don't know what's going on, they become stuck. * It's another thing that anyone building a captive kiosk has to know how to disable.
