In this case, the evdev interface won't solve the issue alone. Some sort
of userspace tool will need to identify what application is expecting that
code and redirect it to that application.

IMO, the biggest LIRC benefit over a pure evdev interface, from user's perspective,
is that it can redirect a keycode to a specific application.

will keep receiving duplicated KET_
