HTTP/2 - at the layer Vlad is talking about - only knows about the
bytes that comprise a request or response.  What Vlad proposes
requires that the HTTP/2 layer look at the Content-Encoding header
field, determine that it *ends* with a compatible value and only then
do things to feed data to the compressor.  That's a massive
architectural upheaval.
