Maybe because at the time 2616 was written, intermediaries were almost only
proxies. But I agree with Roy here, if I install haproxy to load-balance a
squid farm, the proxy-auth headers are for squid and not for haproxy. So it's
not hop-by-hop, it's for the first explicit proxy in the chain. So I agree
with Roy here.

I would personally suggest so.
