You have no evidence of this.
You're not quite tech savvy, are you.
Having options for finer item control is purely a meta-data / code question that would have a negligible amount of memory and zero computation footprint if implemented correctly. They already have the framework for everything needed to support this.
In fact, I'm positive you would be able to fine-tune the item spawn-rates if direct access to the game's memory was possible (through, say, cheating devices and other memory manipulation devices).
People jump too quickly on the "it's a 3DS limitation" bandwagon on every cut they can imagine.
