Right, which is to say that the statement "If we don't bother to use absolute IRIs elsewhere we never hit this issue apart from in that case." isn't entirely true. If the HTTP_HOST is missing, at least the one other thing I mentioned will fail. I'm sure there is some reason why we should support HTTP 1.0 without host headers, but I can't bring myself to think on it.
