Opened: https://phabricator.wikimedia.org/T279530 to track this
Our team was just discussing this some more today and we realized that we may be able to accommodate the content covered by this change with our existing ugettext workflow. Feel free to de-prioritize this task while we verify. We should know in a week or so. I cross-posted this to the phab task as well.
