I'd like to start a discussion about the merits and challenges of
enabling the Translate and UniversalLanguageSelector extensions on
Commons.

FYI, I quick drafted
<https://commons.wikimedia.org/wiki/Commons:Requests_for_comment/UniversalLanguageSelector>
in order to discuss the possible issues, then gain community consensus and hopefully get ULS enabled on Wikimedia Commons

Just a quick follow up on this. ULS has been enabled on CommonsBeta (thanks to Nemo I think!) ; but apart fromThere has not been much activity on the RFC, unfortunately.

I am unsure what needs to be done by whom and when. Should we already try to seek large Commons community consensus? Should the i18n folks comment on the deployment plan before?

Thanks for your answers,

Jean-Frédéric
