Many hub manufacturers increased spoke hole diameter to facilitate machine building.
Don't rely on the spec sheet. Put a spoke in a hole of the hub and pull it out perpendicular to the hub axle. Push and pull the spoke. Feel play/movement? You need spoke washers or a larger diameter spoke elbow. The brass washers provided by spoke manufacturers seem more ductile and easier to work with than the SS ones.

The spoke-hub interface is more than just the spoke hole diameter. Hub flange thickness and angle and the angle and length of the spoke elbow perhaps more critical than the spoke hole diameter to attain the goal of a durable wheel set.
