I think phabricator was doing a decent job at it while it lasted, don't know where they are at since IIRC it got abandoned and then forked.

The best way to track meta history is to have it baked into the VCS, so here Mercurial is king, and heptapod (a friendly fork of Gitlab meant to support Mercurial repos and concepts) apparently does a good job at it since it's used for Mercurial's own development (after they transitioned from mailing lists to Gerrit? to phabricator to Heptapod)
