I wouldn’t say this necessarily means disaster. I believe he just doesn’t want to add more of the same just to have more, like many skin packs, collectables and whatnot in other games. Adding more variety requires to make sense, not become an abundance without a true need. I am sure they are more than willing to add more variety, if it is part of a creative new idea, required for a new content update, or otherwise truly fits the game.
I am sure the new ray tracing technology can be useful, although I personally doubt it is required for NMS to generate realistic lighting considering the somewhat artsy throw-back to a Sci-Fi era. The technology can however be used in other ways as well, which could certainly help boost performance.
