What specific section or headline is this issue about?

Value?

What information was incorrect, unhelpful, or incomplete?

No mention about what stream type Response.body returns.

What did you expect to see?

It would be helpful to show it returns readable byte stream and thus one can also call .getReader({ mode: "byob" }) instead of .getReader() to get the bytes from Response.

Do you have any supporting links, references, or citations?

We are updating the spec here: whatwg/fetch#1593

Do you have anything more you want to share?

Check whether this is supported on each browser by running new Response("").body.getReader({ mode: "byob" }). It will throw when not supported.
