Sorry, I'm also a little unclear about the benefit of another spec. As I an understand it we currently have:

* Specific interpolation routines for different values either defined in CSS Values and Units for common types like <length>s, or in the specification that introduces the type. This was a deliberate change so that new specs can introduce new animation types without having to update another spec, and so that implementers of new properties can easily find the accompanying animation behavior that needs to be implemented.
* Easing functions defined in a separate spec so they can be re-used by animations and gradients.
* A desire to specify keyframe offsets using times (#4907) and other animation durations using fix portions (#4862). Both of these should be specified by Web Animations Level 2 and then referenced by CSS animations level 2 (which builds on Web Animations).

These seem like the right places to me?
