Why does ODT only applies to data bus. Why don't we have on die termination for address command control signals in ddr2?

Why do we use parallel termination(to Vtt) only for address command control signals in ddr. What are the disadvantages in using series termination.

Why do we terminate these signals only to Vtt. Can't we terminate them to Vdd. Is this additional supply Vtt must be required.
