I think this flag name is too generic (and confusable with
simplified-fullscreen-ui). "experimental-x" means we're trying this out and
planning to flip it on at some point. But you're not planning to do that, right,
you're planning to make this a separate mode? So maybe call it
experimental-keyboard-lock-ui or experimental-keylock-ui.

Done.
