Lua modules can load and parse translatable MediaWiki strings, but there is no defined way for storing these strings for Lua modules that are maintained as wiki pages. It is possible to package Lua modules as parts of extensions, and then they are able to load messages from the extensions’ i18/*.json files, but this is done in very few extensions at the moment. Rewriting templates in Lua may be a more robust solution from the engineering point of view, but Lua will not necessarily be embraced by all existing template maintainers, and their cooperation will be crucial to the project’s success, so this cannot be done to all templates.
