There is a fairly strong security benefit of policing it on document-
or even origin-level: it's exceedingly easy to miss an outgoing link
or a Referer-sending subresource (including <img>, <iframe>, <link
It's roughly the same reason why we have CSP, even though policing the
markup is theoretically possible without it.
