Re: [csswg-drafts] [css-animations-2] Composed Animations with existing keyframes (#7574)

I've outlined my concerns with a repeat delay property [here](https://github.com/w3c/csswg-drafts/issues/4459#issuecomment-547181193) and [here](https://github.com/w3c/csswg-drafts/issues/4459#issuecomment-547739865) and I still believe group effects are going to cover more use cases in a more predictable and extensible manner without increasing the complexity of the model.

Most relevant to this issue is that groups extend well to other proposals such as time-based keyframe offsets and percentage-based durations/delays. That is, once you have groups, you have a context for resolving percentage-based times in, something that dovetails into the percentage-based times already proposed for scroll-driven timelines. (In effect, percentages on root effects get resolved against the scroll timelines, where as percentages on nested effects, get resolved according to their ancestors.)
