Right, we did discuss it in the context of allowing keyframe rules to cascade.

This has been out for a while though so changing it might have a compat impact.
Since we also want to be able to resolve the entire cascaded rule for a given
keyframe selector, could we use this method for that purpose? An additional
method to return all the individual un-resolved rules similar to what you propose
could then be added.
