A converter option is “unmapped” — is that a bug to fix or a default to keep?
The question: The Element Mapping tables classify every shortcode option as native / via-CSS / unmapped. Accordion showed 18 unmapped — which looks like the converter is failing. Is a high unmapped count a problem to drive to zero? Should we hand-author “pre-mapping” data, or do we need a pile of real sites to map everything properly?
