Lathe world supp had notoriously unbalanced shit, regular weapons that are simply better than others AND having unlimited ammo. Infitine jump packs, mini-thunder hammers, guardmen and techpriests gaining this OP equipment and implants early, and gaining talents more suitable for RT or BC power level.
As well as introducing Discordants, i.e. hayware psyker retardation.

Well, except the pathetic Pure Form cultists who get poor-quality meat implants or fate points for staying without limbs.

tl;dr Lathe-pattern is expensive, but there are always many more other combat servitors.
You could notice there is Crew Reclamation Facility for voidships, that can produce servitors easily unboard with sufficient spare parts.
