Not really, no.  We can't go and change each place, because many of the
places are outside of our control.
So rather, we have to find a clever way to keep the old code working as
before while still adding the new feature.

Using my proof-of-concept code, I see one of the major problems:

- We need some way to tell define-key whether we want to add a binding
  to ^x (the ASCII control char) or to C-x (the combination of control
  with `x`), same with TAB (aka ^i) -vs- C-i, ESC (aka ^[) -vs- C-[, etc...

- Once we do that we have another problem:
  Say your favorite major mode binds ^x ^x to FOO
  And say some new package adds a global binding for C-x C-x to BAR.
  Now the global binding takes precedence over the buffer-local binding
  from your favorite major mode :-(
