Politicians are not campaigning on this at all. This is a niche topic that only impacts software developers. Nor is this setting out milestones for switching. It’s just advice saying “hey guys, consider other alternatives to C/C++”. It’s a social pressure - there’s no force of law behind this yet. And at most the government can only compel what their own vendors do.
