Maybe people are looking for rules based reasons the Gozanti can carry tie fighters when there isn't one, and the ship carries for them for the narrative reason that tie fighters don't have their own hyperdrive and that FFG simply needed another Epic ship for Imperials and Disney was pushing anything Rebels related?
Honestly, I would be fine with the narrative purpose (hyperdrive) being the only reason for its addition, but I'm sure they'll have thought of something.
Maybe it's all about late arrival. It's left aside at the beginning of the game, and is allowed to hyper in in a turn after the first, and be positioned at any predetermined place on the board.
Who knows?
