Hello 👋

I've just discovered the (obvious when you think about it, but not so much when you dig) behavior of fetch implementations regarding Content-Encoding: gzip; etc.: the body is automatically decompressed, unless you specific an implementation-specific option (compress: false in node-fetch, which doesn't seem to work when we tested it by the way).

The behaviour is very useful to us, but I would like to be able to rely on it knowing it's a documented and stable behavior, and couldn't find this documented in the Fetch Standard, where is this documented?

As far as I understand it it's not part of the spec but an implementation-specific feature, right?
