That is what the draft already requires, if by "compressed" Jonas means
you remove all transfer encodings but retain the content encodings, and
you set .total to zero if the total length is not specified. (There are
even more layers of compression to consider if you don't speak plain
HTTP but, say, HTTP over TLS, since TLS has its own compression layer;
that would be removed aswell under the current draft.)
