Juri,

I thought quite some bit on how we can add in a warning for key binding
change. But as Stefan says, it is probably not worth it.

First of, we would need to create a wrapper function or a wrapper macro to
create wrapper functions for all the commands that we want to phase out
from being bound with the "C-x w" prefix map. The wrapper function will
call the wrapped function and then issue a warning/message in the echo area
saying that that function is already bound to "M-s h" prefix and will no
longer be bound to "C-x w" prefix in future. After that, in a future emacs
version, the final step to unbind those "C-x w" bindings will remain.
