In haproxy we check for "Connection: keep-alive" in 1.0 and
"Connection: close" in 1.1 and I've never had any report of
unexpected behaviour by doing so. Also, I don't think there
is any need for recommending currently working implementations
to stop doing something that has been working fine for them,
because they will simply ignore the recommendation and tend
to consider the other ones with less care.
