Currently these are sent to stdout, which breaks anything consuming e.g. JSON output.

Or suppress non-errors if --json is present?

Maybe as a quick fix. But IMO it is reasonable for the user to want loggy info while piping the result somewhere else. We just need to be more principled with distinguishing between primary and secondary output.

What the packager is printing is not really errors though...

True, but stderr is not exclusively for errors. POSIX says for writing diagnostic output
