Currently, users are allowed to create translation to Chinese (zh) and variants of Chinese (zh-cn, zh-hk, etc.). MediaWiki is able to show "zh" translations in different variants via a conversion function so that users can read "zh" translation in the variant they are used to. On zh.wikipedia.org, MediaWiki shows the variant the user selects in Special:Preferences by default. However, on Miraheze, it shows "No conversion" by default which may force users to make extra clicks to read comfortably.
It would be awesome if MediaWiki shows the variant user preferred in translation to "zh".
