Someone on this site suggested that programs open another filehandle along with stdout and stderr (stdjson) for their json output which struck me as a way to make this work in a backwards-compatible fashion.

Even just a generic stdmeta would go a long way to defining _what_ is being output. Curl is the worst about this.
