Earlier quoted context omitted.
Cause git ain’t user friendly enough for lawyers and they use word not a plain text editor which doesnt make it easy to see the diffs. But yes ;)
Style and substance separation is easy and should be a requirement. Legal is pure text "programming" and what I mean is that the style of the text has zero bearing on the judicial process. The benefits of working at the proper level of abstraction compound. It enables tech like diffs and git, which then nicely solves a bunch of other problems as well. Using Word completely side-steps all those benefits. Sure, you get…
On top of that, all contemporary word processors I'm aware of have, of course, versioning with diffs. It is just different than git (or other programmer tools.) Just as you are using your tools of your trade and don't know much about MS Word, lawyers use their tools of their trade and don't know much about git. It's like saying that editing POs is superior to Trados, because for a programmer it is but a professional translator is going to tell you a different story.
(Of course, everybody everywhere should be using LaTeX for fine-looking documents in all circumstances. No argument here ;))
