I don't know if it's only because it's a committee or because the person at the top J.J. Abrams doesn't care at all about it (it's also why he has kept overusing lensflare in a lot of his "movies")
Exactly, when you're working at his level the resources and knowledge pool to hire people to obsess over the details. It's either a matter of ego, or he just doesn't value that sort of detail.
Abrams cares about realism and continuity to the extent that in his universes you can see events happening on one planet from another with the naked eye
