Intro to Methods making Host header requirement


I was just looking at Section 9 

    The set of common methods for HTTP/1.1 is defined below. Although
    this set can be expanded, additional methods cannot be assumed to
    share the same semantics for separately extended clients and servers.

    The Host request-header field (section 14.23) MUST accompany all
    HTTP/1.1 requests.
...any reason why the Host header requirement is listed here so 
prominently (duplicating text from 14.23)?

Best regards, Julian
