Like we've discussed before, that's just the way things are now. There was a time when there was value in keeping the park an isolated, authentic-ish ozark village with little to break the atmosphere from the moment you stepped in to the moment you hit the parking lot again. The park is so much more than that now and market forces are completely different. People will notice the trees missing and think "how sad", but when it comes time to buy passes they are choosing between SDC, SFStL and WOF and the park with the flashiest new rides wins. I think at least some of the PTB will actually be excited to have a coaster be visible to the roadway coming in.
Being "transported" back to the 1880's is a difficult illusion to keep up, and it has gotten near impossible as the park has grown. A lot of the things that have been lost aren't always lost on purpose, but things have to change eventually as people move on and the old-time craftsmen dwindle.
Obviously there's a lot to build, so I'll hold out judgement until we see the completed product. I'm sure they have a plan for how to interact with the hollow and the rest of the park, hence my questioning whether or not they'll build various walls/tunnels/whatever to conceal it at least partially. This thing could end up being full of theming. The email pitches showed a lot of stuff and were pretty in-depth.
We are almost always pleasantly surprised at what they come up with.
