I think you may be misinterpreting the intent of subsequent series - not to mention their own lack of consistency. For example, you referred previously to the TNG and DS9 costumes being worn simultaneously. This is true, but the DS9 coveralls were never intended or shown as being primarily for enlisted use -- and neither were the 'formal' TNG unis intended solely for officers. The closest you'll get to that is the use of S1-3 spandex uniforms for background extras during the early switch to the newer style during that series. That was merely a real-life cost consideration... Furthermore the original dept-coloured overalls seen in TNG were used by officers and enlisted alike, as necessary.
I'd say out of all the sources, the TOS movies were the most
consistent; at least until that embarassing SNAFU over Valeris in TUC.
Assuming the forward console would prohibit the view somewhat, this is why I tend to think of it as a standing-only station, designed for a specialist to lecture the regular cast about spatial-anomaly-of-the-week; or possibly even to be used by the main cast in conjunction with an overly-large viewscreen as a sort of early "astrometrics" station.
(regardless, it's JUST THE BATTLE BRIDGE, I TELL YA!)
