This goes away if you call it "standard referrer" or something like that.
Maybe just "referrer"?

("referer-origin", "referer-always", etc. is nicer, but then it looks like
something distinct from "noreferer" instead of items in the same set.)

It would fully break the basic use cases of Referer--being able to tell what
server is inlining resources on your server and causing it to be hammered,
and being able to do something about it.  "rel=originreferer" mode doesn't
have that problem, though.

By the way, does this need to consider CORS and the Origin header for <img
cross-origin>?  I'm not fresh on how that works.
