After investigating this topic at length, I concluded that it isn't actually feasible for technical writers to put significant time or effort into generating or curating good first doc tasks. The existing guidelines for good first tasks are accurate; the larger issue is that most doc tasks are not good for newcomers, and that the type of expertise newcomers have may vary in several ways that adds complexity to the work of defining what is a good first task. I plan to publish more about this as an on-wiki essay once I've had time to reduce the existing opinion piece I wrote about this in a Google Doc :-) For now though, in the spirit of new fiscal year clean up, marking this task as invalid as per https://www.mediawiki.org/wiki/Bug_management/Bug_report_life_cycle
