I suspect that this is overengineering : scalable proxies really
shouldn't need special handling for very long requests, and proxies
that need special handling will still want timeouts to guard against
e.g. roaming clients leaving stale connections.

Simply recommending that intermediaries depend on TCP to time out
connections might be sufficient, simpler, and allow room for clean
layering to deal with roaming clients and the like without making
requests larger.
