These changes look good to me!

Pausing before merging to verify with @pquentin about what the missing tests indicates. I'm pretty sure it's fine, but I want to make sure.

It will probably be non-trivial to test async requests within the context of the spec, since they require some special timing, so I am not surprised the spec does not test them. That said, please tell me if anything needs to be added here.

[pquentin]

Can we please make the body binary as done in #3639? The current representation isn't usable for typed client. (The current behavior of "return structured response, unless it's ready, then you get binary data" is unfortunate.)

The backport to 8.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-8.x 8.x
# Navigate to the new working tree
cd .worktrees/backport-8.x
# Create a new branch
git switch --create backport-3643-to-8.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 585f69729291cfda4acb5c47a7466abe6c42e9c0
# Push it to GitHub
git push --set-upstream origin backport-3643-to-8.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-8.x

Then, create a pull request where the base branch is 8.x and the compare/head branch is backport-3643-to-8.x.
