Nobody's talking about anything being "doomed," though.
It's about personal preference, as well as holding the company to the standard they're aiming for (we'll know more about the standard they're aiming for once they really start promoting the park).
And also, given that Monsters is by far the land I care most about, it wouldn't feel great if it's also the one where the attitude of the designers is "Eh, who cares if people can see these backstage areas."
IF.
