It would be really great if the user interface is
something that can be
set in user preferences in other projects than just zh: ; it would make
a lot of difference in data driven projects like WikiData, WikiSpecies
and with a database backend Wiktionary.
It is not specific to zh. But the zh site supports multiple variants
in the content, which is uniq atm.
I would prefer to have this only for registered users
because it will
prevent people changing stuff to their local language (not a good idea
in the datadriven projects). When registering, the user would be more
aware of what the project does and this would prevent a lot of these errors.
I think there is internal measurements to make sure only sysop can
modify the mediawiki namespace. The UI switching itself is per user,
so you and I can use different UI languages at the same site, for
example.
