I would like proper browser toggles. But they are not here, and as long as they are not here, you should always include a toggle. Why is it not acceptable to require JS to be acceptable? You can always provide a pure CSS fallback for those who make the deliberately make the tradeoff of disabling JS. But don't force everybody else to change their whole system color preference just for your website when three lines of JS allow you to create a perfectly integrated toggle.
