Background

Similar to T137127, I propose we add a {{int:done}} and a {{int:not-done}} messages in the WikimediaMessages extension. At least two WMF projects are "international": Meta-Wiki and Wikimedia Commons. It is not strange that we attempt to translate the templates to make the project more international. The same happens with the templates: {{support}}, {{oppose}} and {{neutral}}, as well as some others; which can be added as {{int:vote-support}}, {{int:vote-oppose}} and {{int:vote-neutral}} as well.

Internationalization efforts have been intense both at Meta and Commons, and have often included hard work with templates (such as {{Autotranslate}} or other complicated wiki syntax to make it happen).

Pro/Con I see so far (will modify later if I find more):

Pros

• Translations avalaible for this templates without the need of complicated wiki syntax or hundreds of subpages or large {{#switch}}es. The template text will just display in the language the user has in their preferences.
• Performance improvement?
• Easy translated code for the templates through translatewiki.net; with regular updates.

Contras

• Somewhat broken sentences. It's weird to see, for example: Hecho (es). I have deleted the page (en).
• Risk of external vandalism. A malicious user could vandalize a translation at TWN and have it propagated through our sites, with reversal taking hours until the next localisation update.

Regards.
