The request line is a hop-by-hop message, right? So it couldn't be used as a signal for end-to-end headers. How many middleboxen out there are likely to inspect the request line only as far as 'HTTP_VERSION > 1.0' and then barf if one of their response headers looks weird? Although I suppose the answer is not that different from: how many will forward X-Accept-Fancy-Headers blindly and then barf... Pity there was no strong hop-by-hop vs end-to-end flag on headers.
