When creating a new superflat world, that world's spawnpoint can be over 1000 blocks away from the centre of the world.

Not that it matters very much, but that seems to be inconsistant with default world spawnpoints, which never seem to be more than 400 blocks away in each axis.

Anyway, it would be nice if superflat world spawnpoints were always at (0,0,0) seeing as they are generated the same everywere, if just for pureness' sake.
