Some templates don't have structured author / editor fields and just include them all in a list. There was a request to flatten the fields.
Ideas? This goes back to the beginning of how we decided to write the template data maps and corresponding 'mediawiki' data structure.
We definitely shouldn't corrupt the existing 'mediawiki' format, especially since doing this in the backend just duplicates data. Anything like this should be done further upstream. Ideally, at the template level, but wondering if anyone had any opinions before marking this declined :).
