While in DRM backend, all weston_keyboards seem to use the global keymap.  It can be changed by setting up `weston_compositor_set_xkb_rules` before `weston_compositor_wake`. After that, there is nothing I can do. It is used to be possible to call `weston_seat_update_keymap`, but It is now an internal API. Even by that I think it would be a nasty way to change keymap.

Sure. But why do you say that `weston_seat_update_keymap` is a 'nasty'
way to change it?
