This should lead with the animation-trigger property, as that is what makes an animation to be a triggered animation.
That animation-trigger can then be a timeline trigger, which makes that triggered animation be a scroll-triggered animation.
(For completeness: the spec is also busy with defining event triggers, but that is still WIP and has not shipped yet)
