If CC Mode has problem with these hooks, it could bind them to nil
around the call to self-insert-command, couldn't it?  That'd be much
better than making any globally-visible change in behavior, for which
we cannot possibly know the unintended consequences.

In any case, please let's not make this change before the emacs-28
branch is cut, as it can potentially disrupt many places.
