> Right. That’s the good part of your solution - it’s atomic. But I was thinking about a scenario where two users open the document (version 1). Each of them makes one change (maybe one removes a section and the other inserts a comma). Each of them have version 2 now, but they are two different versions. With timestamps it’s very unlikely.

It occurs to me that you might find this Elm Europe talk interesting:
