TranslateWiki has been working on translating Phabricator, but the translations only apply to the WMF's install of Phab. It would be super cool for us to upstream these translations and make them a part of our codebase.
A highly unfortunate side-effect of T15077: Rebrand: Tracking task is that it will invalidate a ton of translations. My guess is that upstream did not want to maintain these translations as part of the release product, possibly due to not requiring translations be part of the Phabricator release process. If we pull them into the Phorge codebase then we would likely need to update all translations for any text changes made during development, prior to release. I think it would make sense to host the translations in a repository here but I would worry about them quickly falling out of date. Handling of translations is likely a larger-sized project that we would need help managing.
Anyone aware of tooling that would help in managing translations? I've looked briefly at Pontoon which is made by Mozilla for translating Firefox - https://mozilla-pontoon.readthedocs.io/en/latest/. Something like that might be useful for reviewing text changes and crowdsourcing translations.
