Yes, we agree about python-mode.  The default for CC Mode must be on,
otherwise automatic indentation is broken.

just as there isn't a global default for `font-lock-keywords'.

If it's not been explicitly disabled by the user, electric indentation
must be on in CC Mode.  Otherwise automatic indentation doesn't work.
