That's another "axis" for the enumeration for [--error-display](url), unless you'd define it to be that if you're asking for JSON output, you just should get details in the JOSN and no details or summary to stdout. It's not a terrible idea, but I'm not well informed about the variety of ways folks currently use `--verify`.
