Yes, but since then we've heard people wanting to optimize their
connections to the other side of the ocean. GET was slow over low
latency connections, but if you have fast - cached - local connections
and one low bandwith WAN, you'd want to have GET and a proxy. Should
we provide an option to enable GET again?

Yes, but that assumes we'll have pipelining. Do our current
dependencies support that? BTW: I'd write the pipelining bit if I
knew where to start...
