I'm not sure what is left to be done https://github.com/plone/ploneorg.addonlisting but @Alexander_Loechel would know!
Turns out he had a PR waiting, so it's close https://github.com/plone/ploneorg.core/pull/251
@Alexander_Loechel and I have been working to get the addon listings package onto Plone.org. There are some tweaks to make still but we have made good progress today!
