Hah! I like how this was there and just not wired up.

I'm not a fan of error messages for routine conditions. If this is
really a "shouldn't happen" case then fine, but it looks like this will
emit a message every time you have >=1 disabled keyboards and hit
CapsLock on an enabled keyboard. If I'm reading that correctly, can we
just drop this message?
