I am not aware of any keyboard that repeats its events upon holding a key.
Repetition is usually implemented in a toolkit handling key events. A keyboard
typically sends a single "pressed" event, and then after you done holding a key
it sends a "released" event.

Here's a proof: I run `libinput debug-events --verbose`, then hold `j`:

    $ libinput debug-events --verbose
    […]
    -event6   KEYBOARD_KEY            +0.000s       *** (-1) pressed
    jjjjjjjjjjjjjjjjjj event6   KEYBOARD_KEY            +1.280s     *** (-1)
released
    […]

See, there are repeating `j` on the screen, but it's created by the Qt toolkit
of my Konsole terminal. Keyboard sent only 2 events: `pressed` and `released`.
