To sum up, the Highlights section will be maintained and reviewed by the Documentation Manager (see proposal:New Documentation Manager role). Anyone who wants to update the Highlights can open a Change Request or ask on the xwiki matrix channel.
Please note that “What to Highlight” is quite subjective. The intention is simply for contributors to use the Common Criteria above as inspiration, so everyone shares the same reference point when proposing changes.
The updated doc guide: Create Landing Pages.
Thanks!
