Let's not rule anything out here as I thought I was a bit crazy bringing it up in the first place.
A while back I thought the comet of
Starfall Stardust Racers and the carousel had a story or some kind of thematic connection. If you look between the berm and the coaster entrance you could see what I interpret as an impact zone of a meteor.

I wonder if we'll see something as part of the ceremony for the Chronos? Or it's own mini show within the lagoon around the carousel which might involve the coaster too.
I think the half pipe does have some use. It's hard to tell from the angle of the shot but I believe it allows riders on the carousel to easily see the comet statue of the coaster if you were too look out in that direction.
It makes me think it's possible we'll have some kind of narration on the carousel to give some light exposition and use the areas surrounding the carousel as storytelling components. Even if it's nothing outright explained in the park it seems like there's some intention to the design and how the sight lines of the two rides are framed.
