Yes, Absolutely true regular users of the API.
But in the particular case of JMeter, can this happen ?
In the particular case of JMeter, users usually want to:

   - Check that server response was Compressed or not (ie what were the
   original headers) and the size of the original response (headers + body
   compressed if applies)
   - They also want usually to check some data in the response through
   Assertion, which means it needs to be uncompressed

Usually also, users will compare headers in the browser with headers in
JMeter to see if they match, and it will be suspicious if they don't.
I am afraid a lot of plan and users expect these headers to be here (but
maybe we can ask on user mailing list and twitter)

Yes option might be interesting although it is then hard to know if
received response is OK or a 404 page masked under a 200 response code or
similar cases.
