It's not clear why you think that's all you can conclude.  I would
have concluded that the origin server couldn't find a resource by that
identifier at the time of the request. Maybe I'm not understanding the
nuance of "doesn't exist" vs. "not found".  404 is saying it doesn't
exist *at the time of this request*, right?
