This is also future proofing the game (along with removing belts). Every item that can be HQ has two entries for the same item basically. At some point this is going to balloon into a massive amount of items. They're already doing a stat squish because values are reaching amounts so high it's in danger of triggering overflow errors. By getting rid of HQ items that you can gather now, this is ensuring that game (under its current system now) can survive just that much longer (before a complete and utter overhaul of the base code - which would basically kill their update schedule).
