Even without a proxy, 1.1 headers are likely useful and should be sent.  A
client may not be comfortable advertising itself as 1.1 because of a few of
its deficiencies, but it may implement some of the features the new 1.1
headers deal with, like byte ranging (Accept-Ranges), Cache-Control, Vary,
etc.

Congrats on the RFC number everyone!  Nice way to start a New Year.
