should homing be using offsets like z_tilt?

Z homing, centers the nozzle , so probes offset (not dead center) for the final Z homing. Z_Tilt.... uses the probe points from printer.cfg., as to for the mesh point locations. Why doesn't normal homing use that same offset.
I pose the question as what if there is a mesh diff between the offest point and the Z homing centered point that one would think sets the ref for the mesh center. Wouldn't that possibly add to mesh thickness issues across the bed?
