This doesn't scan to me. Symmetry between requests and responses is
unrelated to ordering of content. Interrupting a body is also unrelated
to this point. Specifically interruption requires a full duplex
connection which we don't have.

And duplication is something we shouldn't embed in the protocol. HTTP
does with trailers and its pretty fugly the complexity it drives.
