Coming super late to this discussion I know but I _really_ like Tab's variation on the original proposal. I think you can do pretty much anything you need with it, correct?

interpolate(18px, 24px, calc((100vw - 400px) / 400px), ease-in-out);
interpolate(red, blue, var(--slider-position));

The form would be `interpolate(from, to, fraction, easing)` and `fraction` would be automatically clamped between 0 and 1. You'd need unit algebra to use `calc` in the first example but I'd be suggesting using `style.setProperty('--slider-position', mouseX / elWidth)` or something in JS for the second.
