Yes, I should have elaborated on that. Quite right, the convention attendees seemed to elevate the importance in the minds of the "others", which seemed to convince them that they should have been billed at the same level as the Big 3. The writers did take an occasional stab at exploring their characters to a small degree, but egos and the passage of time skewed the reality of the situation. Yes, it was never considered an ensemble. I think they tried to rectify some of that when they were writing for TNG, but didn't really get there (IMO) until DS9, which felt truly like an ensemble show. VOY? Meh...That's the thing, though. TOS wasn't an ensemble cast. It was a show about three main characters. Period. The remaining characters were there to help move the plot along. It was structured like a typical 60's TV show would be structured. Yes, there were certain episodes where the supporting cast got more to do, but most of the time, it was supposed to be Kirk, Spock, and McCoy heading off to planetary adventures while everyone else sat around the bridge and waited on them.
Sometime during Trek's great syndication run during the 70's, and particularly the rise of conventions, many people associated with the show, not the least of which was Roddenberry, began rewriting history as to what the series was. Fans began elevating anyone who appeared in the show as though they were all legendary members of a big ensemble show. But that's never the way it actually happened.
I think I remember seeing that extended scene a long time ago. Yeah, it was not a well done bit of dialog and I was glad that it was dropped. Sadly, Takei really thought he could get some serious self-promotion mileage off it, though, leveraging it (and other perceived slights) to manipulate the others against Shatner to boost his own dwindling relevance. Fortunately, I think that has all played itself out, for the most part. Everyone knows all the backstories and drawn their own educated conclusions about the various facets of "The Feud". Based on what I've seen, it would appear that Shatner came out on top, although I'm sure there is still a core group of Team-Takei party-faithful who will never be convinced, and still think a "Captain Sulu" show is still possible if Paramount would just listen to reason!If you've ever seen the scene or heard the recording you know this is a BS story against Shatner. It's a terrible line and the reading of the line wasn't even good.

100% agreed.When it comes to Shatner, I don’t trust a single word that comes out of George Takei’s mouth.
I’m sure there’s some truth in his vitriol, but it’s mixed in with so much of his own personal biased bullshit that it’s impossible to differentiate fact from fiction.
A very unpleasant, embittered individual.
