WUG (Wiki User Group) China is the first WUG with its own wiki on wikimedia.org ?

I see quite a few of chapters also missing such as be, ca, etc.

I dont think it is useful to restrict wikimediachapter_family.py to be 'chapters' only - separating it to country/region based codes is sensible as they have a different standard governing the subdomains / 'codes' used. The organisational status of the parent body is not particularly useful in pywikibot. e.g. what happens if a chapter is delisted and becomes a WUG? Does the wiki change 'family'? No, that seems silly.

So IMO we should rename this family again (it was renamed recently) to something a bit more generic, and add any missing region based affiliates, including WUGs e.g. China. The full list can be extracted from https://meta.wikimedia.org/wiki/Special:SiteMatrix#mw-sitematrix-others (by guessing which prefixes are region based codes), however InitialiseSettings.php and other config files may be easier ways to obtain the correct list.

I believe co.wikimedia.org (for Wikimedians of Colombia User Group, included in wikimediachapter_family.py) is a WUG wiki before WUG China.

So IMO we should rename this family again (it was renamed recently) to something a bit more generic, and add any missing region based affiliates, including WUGs e.g. China.

Maybe also future Wikimedia thematic organizations wikis hosted by wikimedia

Is this rejected? it's been a year soon
