No it wasn't. Ships worked a certain way. The manual for the Enterprise D existed before the Enterprise D was shown on screen. If you follow along what the crew are saying about the ship and its systems you'll eventually get a "feel" for how it functions.
What neither Rodenberry or Berman explicitly didn't want was to have the characters spoon feed how the ship works for the audience. They were supposed to talk professionally like they knew their jobs and the tools they worked with.
The whole breathless fast-talk with meaningless bullshit is a modern thing from writers and execs who don't give a crap about sci-fi.
It doesn't need to be hard sci-fi. It's just significantly better and more thought out than most sci-fi, and especially better than what Abrams and Kurtzman made of it.
