There's still A LOT of prefab rockwork coming to Fluffy's area, and that hasn't even begun.
The prefab work that goes around the spike is also meant to cross over the track for the last bit as well, blocking view of that maintenance building a little. If it was cut, something else will still need to be placed there.
Don't think it was cut though, as other prefab themed rockwork, vines, and fake trees are still not on site yet from other areas of the ride. Seems like last step stuff that can't be installed till after the pull through to me.
