Yes. And the argument is that if a server can do gzip, it can do
deflate as easily, so there's no point to give it both options.

(Compression of requests is probably out-of-scope here, but since
http/2 server implementation is a heavy task requiring abundant
resources to accomplish, mandating servers to accept compressed
requests may not be too much to ask? Or is it the last straw that
breaks the camel's back?)
