Issue: ''Special:MyLanguage/'' Could be added by help page editors writing in /en.
What we want to avoid: translation should not vary for terminology/words that apprars across documentations / wikis. The system’s functionality needs to be mastered by document writers.
When: if the documentation writing be pushed to internationalization.
Who benefits: translators and proofreaders, and readers of course.
Example case: [[:mw:Reading/Web/Desktop_Improvements]].
A kindhearted translator who had added /ja into translated text; it triggers persistent _need update_ warning.
Involved: tools.watch-translations[at]tools.wmflabs.org, which is a subscription that warns proofreaders to check recent new translations.
