To be fair, I think most of the more recent changes are just backporting engine upgrades and stuff from the new game they’re working in. That’s still a lot more effort than just saying that, but it’s not like they’re developing explicitly for NMS anymore.

It also let’s them test the upgrades in a real environment before the new game launches, preventing another mess at launch. It’s a smart use of resources, keeping people discussing how well you maintain the old game going into the new game. It’s free press, along with probably more sales.
