Since HTTP 1.0 has no Connection header at all, the proposal "breaks" http 1.0 either way, whether we choose "Keep-Alive" or "close". Given that, "Keep-Alive" seems the better choice. The defined behavior for http 1.0 is that the connection is closed after every request, so we either stick with that or we don't.
