As of RFC 7230 et al, it is officially now optional. Yay!

As of Squid-3.2 emitting HTTP/1.1, its use in preventing 1.1<->1.0
translation errors is greatly reduced. Yay!

It is still important to avoid forwarding loops though. So interceptors
and complex hierarchy installations are advised to enable it where
possible. Just for safety though, not RFC compliance.

[somewhere down on my to-do list is making Squid be a bit more flexible
that on vs off for that header].
