@birtles Is the recent work done in relation to #5125 good enough to close this?

I guess we probably need to add something to CSS Animations Level 1 specifying this?

Ah, OK, should we move the keyframe generation algorithm from css-animations-2 to css-animations-1 then? That's basically all we need in css-animations-N, and then the rest is handled by calculating computed keyframes in web-animations-1.

Perhaps except that algorithm as it currently stands uses Web Animations concepts and is tailored towards Web Animations keyframe notation. Level 1 doesn't have a dependency on Web Animations so we should really tweak that algorithm for level 1 (while keeping the existing text that is based on Web Animations in level 2).
