I really like the idea. I see how it can be confusing or even annoying to users to find a link to documentation not in their language but I think it is perfectly reasonable to still have it.

Maybe this would be out of the scope of discussion for this issue. I imagine that this would be especially useful in a dashboard with other relevant links. With other changes like #2906547: Add links to Drupal.org contrib project (and issue) pages to module listings in /admin/modules, I think the admin screens can build a stronger link to resources on d.o for content managers.
