I use a browser (Charlotte, for VM/CMS systems) that does exactly that
to store its bookmarks.  Bookmark references come through with
"Referer: file:///HOTLIST.HTML.A1", which wouldn't make my company's
access control very happy but is still quite correct.

FILE: comes sort of close, though, as it has an somewhat opaque meaning
if you can't read the user's filesystem.

Nor do I.  So long as REFERER is still a part of HTTP, and not
deprecated, I'm happy.  Our customers who use REFERER will either do so
or not depending on what makes sense for their business, and we will
continue to provide the capability for them to do so.

Agreed, if a URL's response says "don't identify me as a REFERER",
we can't make it a MUST at this time, but we can require that any
client that understands the "don't tell on me" header field MUST comply.
And naturally, some sites will respond with "Sorry bub, I need to know
who told you about me."
