I'm just not at all certain that this kind of policy issue belongs
in HTTP at all. What if, for example, there were an HTML HEAD element
that could contain a site's policies or links to them, and that
before actually storing any cookie to disk, the policy could
be determined?

Putting this kind of information in the protocol seems like it violates
the boundary between protocol and application in a way that doesn't feel
right to me.

I could imagine a kind of option where a client could ask a server
for the LINK to its policies for a given realm, which might be an
OPTION request or some other such thing, but I'm not sure that it is
a protocol extension to HTTP.
