That's not the conclusion I came to, which is: You should feel fairly
confident in binding C-g as a quit character in your code, but
Emacs itself should continue to fully support current-input-mode/
set-input-mode -- unless and until a decision is reached to deprecate
the QUIT functionality they provide.
