Sometimes it feels like people had the entirely unrealistic expectation that they were going to be landing on Planet Skyrim and wander around a handcrafted world full of quests. And then have a completely new experience of the same scale on the rest of the 999 planets.

It was clearly put in to play interspersed with the questlines and for some endgame looting, but some people wanted to be able to just wander planets endlessly as if it could possibly have the scale of content that would make it worth playing like that. Maybe they'll come back when modding lets them insert hundreds of new POI prefabs off the workshop into the procgen pool.
