SC is at a stage well before an true alpha where they slowly implement systems and get them to work in the game, it has many of its core systems inplace so claiming it has non is just blatent lying, they have plenty of experience developers from all stages of development so they know what they are doing as is proven by the version of the game that is available.
Making a space MMO with detailed planets, full ship/stations interiors is probably the hardest game to ever make, and thats why we dont see many space games come along often since the community is much smaller no company will take a risk.
