A few thoughts... Is it an error to not include this header? I'm not interested in the subtle advertising to log readers, so it doesn't really matter to me what is says.
What's the behavior when there are two Server headers? Because you can just as easily pass another one in the optional header list. I don't like the idea of a parameter or another field in the response data structure, but maybe I should just add an optional argument to response/xexpr and then remove the automatic insertion in the code you quote.
