For archery sights, why is it legal to have lit reticule sights on a rifle and not a bow!?

Wouldn't it be better if the hunter were sure of their target? Lit reticules were illegal in the past on rifles so why change the rule for rifle and not bow?
Answer: 
The Commission Rule states that hunters may not take big game with archery equipment "with any electronic or tritium-powered device attached to, or incorporated into, an arrow, bolt, crossbow, or bow (except nonmagnifying scopes containing battery powered or tritium lighted reticles may be used by disabled archery permit holders)."
