why CSRS is not only in center 72 subcarriers?

As PSS, SSS and PBCH are present only in center 72 subcarriers, but why CSRS is present throughout the bandwidth?

CSRS location is dependent on cell's Antenna configurations.each cell has uinque Antenna configurations
CSRS is pilot channel - UE estimates the downlink channel conditions based on this signal ,Hence this is spread across the bandwidth.
