I have a speculative thought on why they're focusing on obstructing the view of visual, and I wonder if it has to do with security teams wanting to restrict the ebb and flow of what people see in guest-facing views, while also preparing measures that allows them to keep certain things post FFN to have soundproofing efforts pre-prepped and ready to go.
Makes me wonder things in regard to this year's event, in a good way. Hopefully we see this movement happening with Jurassic's venue--and that should give us confirmation.
