Why do we need both status code and phrase code in a http response message?

In the first header field of a http response message there is a status code (Eg.200,404,400) and phrase code(e.g.OK, NOT FOUND, Bad request). When we have a status code already, why do we need a phrase again? Wont that cause extra overhead?

A) Technically, that is not a header field. The first line simply is special.

B) It's not needed and optional, and yes, it causes overhead.
