While this is true, I think it's fair to call DS9 an outlier though, since it was the onlyshipspacefaring construct among the main series group that had multiple factions vying for control rather than being beholden solely to Starfleet (even nominally). The Cerritos doesn't have that same excuse - though of course, Mariner's discord seems to be something that is either unknown to or being glossed over (for obvious reasons) by the ship's brass anyway.
