I'm going to leave them intentionally long in the final game, though I am going to add some life and purpose to them with extra rooms and randomly-generated NPCs walking through them. But one of the major themes of this game (at least, initially, lol) is the vastness of space, hence the absurdly-large world map. The size of your spaceship reflects that, to highlight just how small/slow the player is in comparison to the space they're travelling through.
