We do something very similar in the "real world" with data acquisition systems. But we are using a HTTP/1.1 _compliant_ server - and so the only option for compressed range requests was to do gzip transfer encoding.

You tell me "real-world" examples of Varnish using Range with C-E gzip and there you'll have all the examples you need.

Not our goal at all.  _We just want to make sure HTTP/2 doesn't lock out something you can already do with HTTP/1.1._  As the HTTP/2 spec is currently written, you can't do compressed range requests because gzip transfer encoding is disallowed. But at the same time, if we can help eliminate the misuse/abuse of C-E gzip, that would be great too.

*Don't forget that HTTP isn't just for browsing the web.* Sure there are other protocols out there (e.g. FTP, SMB, CIFS, ...), but they all have their own issues (overhead, security, etc.).  But HTTP is the most widely used protocol in the world and has so many nice features that it gets used for lots of other purposes besides browsing.
