Seeing TARDISes won't act as chunk loaders when U47 is out, I'm pretty sure that lag caused by loaded chunks and cases of chunk corruption would drastically decrease. I wonder if the mob spawn rate would be back to normal, and whether mob and animal farms are allowed?

If you want to ask about credits and stuff, I think if passive mobs and mobs spawned by mob spawner won't drop credits, the cheat could be solved

Please, don't remove credits being dropped by passive mobs! I get food and money from them! I need that!! XD

 I proposed that the mob spawn rate would be back to normal, and only credits would be removed from the passive mob's loot table, so you don't have to worry ????

 That's a shocking idea, there's a reason things at the shop are pricey

 That's why I balanced the number of credits mobs drop. Credit drop rates can be further decreased

It's still a bad idea, the credit drop is fine.
