Good point, see https://github.com/w3c/csswg-drafts/issues/1284 which adds a 'midpoint' - somewhat oddly named, it turns the linear interpolation between adjacent color stops into a curve, effectively moving the point at which the midway color is reached to be earlier (curve up) or later (curve down). This is way easier to understand with a diagram, of course. (an interactive diagram would be even better).

Being defined by a single point, it is less flexible than easing functions which are defined by two points, giving S-shaped curves as well..
