Not the same as a wiki or a tech spec or whatever but detailed, searchable pull requests go a long way towards good documentation. And it's something any dev can match up with code with git blame. Sometimes pull requests are vague because there's a lot of discussion happening in a different channel. That's fine -- just make sure the discussion is happening in a form you can easily link to, like a chat message or mailing list thread or meeting notes or whatever.
