Removing the correspondence between ctrl modifier and the ASCII control
character would at the very least break the xwidget code in a
non-trivial manner, a and probably a lot of comint-related code too,
just to name a few.

It would also break `teco.el', a fun toy implementing the TECO text
editor inside GNU Emacs.

I have no interest in updating the xwidget code if this change is made.
