That's just one of the typical nonsense statements that have been made about exploration overhaul, mining overhaul and the better USS system. And basically everything else they've added to the game. Some people constantly claim FDEV would just talk about things and never implement them and as soon as they get implemented people forget that they asked for it and demand something else.
But there are plenty of things that Frontier have talked about and haven't implemented, ship damage models, gas giant atmospheres, etc.
After nigh on a decade of development, wouldn't you have expected more than the original base game release?
