If the intent is that the header is to be optional, or optional only for
specific methods and required for others, then that should stated
explicitly using RFC 2119 language. The current wording, "the newly
created resource can be referenced by the URI(s) returned in the entity
of the response, with the most specific URI for the resource given by a
Location header field," implies that the client can assume the Location
header is always there, which is why I interpret it as being required.
