It makes perfect sense, constantly fighting playable characters throughout the story mode gets rather stale and too forumalic, having NPC fighters throughout the story who've already got a somewhat functional moveset from the previous game is incredibly easier than creating new movesets for them and new characters who're just made to be NPC's, Tanya was an exception as she was always intended to be playable in the game, notice how NPC Tanya has a more functional moveset than Rain and Sindel, she even has access to some of her default specials, she re-used some of Kitana's animations, but that's actually understandable due to them not being finished with her development at the time.

Your logic of Goro doesn't really backup any form of argument you're trying to pull, Goro was intended for the playable roster, Sindel and Baraka weren't because they weren't (at this time this is before they say who the new foursome are) intended to be part of the roster, thus making another moot point regarding it.
