It would probably make even more sense to mark this as an experimental
feature for now (i.e. prefix the description with "(EXPERIMENTAL) ", so
that users will have a harder time to miss that vague statement at the
end.

Once the feature stabilized enough, it would probably make sense to start
versioning the JSON format (`--json[=<version>]`, defaulting to the
latest).

That would make this a pretty useful feature not only for debugging, I
would imagine, but really would set a precedent for a better "API" for
3rd-party applications to use than the current one.

Thanks,
