Well, "creator intent" undeniably shows that the lift is supposed to be in the little "nub" at the back of the bridge dome. That is established on MJ's own artwork. What artwork from MJ, or anyone else on the production staff for that matter, which was created during the run of TOS, establishes that the bridge was supposed to "face forward?" Stating "what they likely would have said" is just silly. I can just as easily say "they likely would have said that the bridge was manufactured from pressed pasta" and there is absolutely no less support for that statement than there is for the one I'm addressing. Either they said it, or they didn't. Either MJ drew the "nub" as being the lift shaft or he didn't. If he did (and yes, he did) then it's the lift shaft... regardless of any made-up "what I think they really meants" we might come up with.
