Because, frankly, it needs it. At the end of Automatron, you can pick up a blueprint (Optional, not given to you) that lets you build an eyebot pod to send eyebots out into the wasteland to find resources/explosives/ammo for you to scavenge. It's not enough. The amount of ammo scavenged needs to be multiplied by at least three, and I'd like by five as an optional file. You search for 5mm, but get under 200 per search. For a minigun, that's... Not enough. Fusion cores, one at a time. This is annoying, given that it's a reward at the end of a paid DLC with significant combat to get through... It should be a greater ability. A secondary function it needs is more search-ables. Need to be able to search for Fusion Cells, Cyrolater Ammo, and AB Rounds, for a start. But primarily, yes, needs at least x3 as much ammo/resources per radiant quest as the base game.
