Yeah, symmetry is overrated.

Git's merge is already symmetrical for two branches being merged, and that, in and of itself, often leads to problems.

It's completely unclear that extending this to multiple branches would provide any goodness.

It means anyone can fix the conflict. Including a server side AI.

If it is doing what I think CRDT does, and tracking where the user clicked and what they typed, it sort of carries a bit more syntax info. It has a chance to get it right. And often since it does something it turns a figure this shit out with review this.
