Why not address security metadata for user-agents?  For example, it
would be eminently useful to be able to express X-Content-Type-Options
[1] and X-Frame-Options [2] in a centralized metadata store instead of
wasting bandwidth on every HTTP response (as Google does for
X-Content-Type-Options).  I don't think anyone doubts that we're going
to see a proliferation of this kind of security metadata, e.g., along
the lines of [3].  I don't see the point of making a central metadata
store that ignores these important use cases.
