What’s being added to A72?

Maybe I’m tardy to the party but while riding WindSeeker today, I saw some structural work being done to a part of the backstage area outside of Area 72 near Orion.

You are late to the party. Everyone knows that is the first stage of construction for Step Sister of Bavarian Beetle!

I thought it looked like a new roof to cover some equipment. Knowing what's stored in the giant tank next door and/or the building on the other side could be a clue.
