My wife is a laywer and she and her colleagues (and the other lawyers they are working with) pretty much base their workflow for revising documents on track changes. I've never heard her complain about it.

You know how they do that right, stay in online chats and ask who, how, why, when. Awful waste of efforts
On Office 365 at least, it does tell you all of those things.
