It's reusing the in-memory cached keymap. Since it doesn't think
you've changed the Xkb options
(evdev/evdev/us//terminate:ctrl_alt_bksp), it's using the same keymap
it got from xkbcomp on the previous run. And yes, you have 4 keyboards
(3 by my count) in the sense that the kernel is presenting that many
devices with keys.

The real question is why Applying InputClass "keyboard-de" doesn't
change the layout to de even though it's the last class merged in. I
thought this log would give more info about how the settings are being
merged together, but I guess that part never really got done.

Looks like Peter confirmed it's a bug.
