You've highlighted one of the primary challenges with such a filesytem. Determining what files have been modified as a _meaningful user action by the user_ (determined by the user thinking it was meaningful) and _what changed_ would be a very hard, but incredibly valuable problem for the user. I think fundamentally the success and adoption of a timeline-oriented filesystem leans on new user experiences that have yet to be designed.
