I think it is because it helps to differentiate connector (client) from component (user agent). Much of the HTTP spec deals with stuff that regards correct connector implementation, but, e.g. headers such as User-Agent or Accept apply to the user agent and its capabilities.

I think that the HTTP spec can contribute to correct use of HTTP by emphasizing that a user agent is a software component that takes actions on behalf of a user and is not just constructing HTTP requests and receiving responses (that is what the client does).
