Given that they don't (often? ever?) advertise Light No Fire alongside the NMS updates, I'd say that the updates into NMS are large-scale playtests of LNF engine updates, game systems, or both, rather than marketing.
Yeah, I meant the marketing effort for No Man's Sky since that's where the money is. They need to continually attract new players.
