I agree that changing prefers-reduce motion to automatically apply is not backward compatible and also prefer a solution that can be used for all animations.

I like the idea of having `forced-reduce-motion` that would forcibly reduce the motion of author provided animations. This would be backward compatible and allow User Agent to interfere on behalf of the user even when authors have not done the right thing.

For example the User Agent could change the animations that modify certain properties (transform, top, left, height, width, etc.) to do a [discrete](https://www.w3.org/TR/web-animations-1/#dis) interpolation between the initial and final value of the keyframe effect. Basically have them do a single jump from initial to final value in the middle. That would leave the animation final output intact while reducing the motion.
