It's a great thing if those changes live in their own repo and not mixed with changes to the code itself. Actually Jira has been doing that for a while now by offering the history view with a timeline for each change, also GitHub shows edit version for files as well.

But having everything in the same repo will remove this decoupling and will let developers get involved in that chaos as it's part of the repo history.
