You appear to be focused on absolute utilization efficiency. CGA approaches
trade space efficiency for authenticity. Approaches like using RFC3041
addresses for everything trade utilization efficiency for immunity to
scanning attacks. 

Maximizing allocation efficiency is simply one dimension in a
multi-dimensional problem space.
