I imagine the biggest difficulty in these situations is dealing with other people: just like LaTeX might be better for certain kinds of documents, but the world still wants MS Word. But if we look narrowly at functionality, it seems that plain-text and git might be better for strict audit situations. In a Git history every thing you do has to has a "paper trail" in the form of a hash chain (admittedly using an outdated hash function). People can only "uncommit their nefarious <anything>" is along as those transactions never found their way to someone else' hard disk.
