Dan, While I don't disagree with you on a theoretical level; practically, this is necessary. It must be possible for a User-Agent to discover policy for a resource without requesting that resource. Additionally: * HTTP headers are difficult to configure on many servers, and/or publishers don't have access to a means of controlling them * sending an HTTP header on every response is a (to some people) signficant and needless overhead to serving traffic (particularly if they serve a lot) * HTTP is but one protocol on the Web; its use is not required. URIs, however, are common to everything on the Web. Using a URI to associate policy seems more sensible in this aspect.
