The benefit of using a crdt for this is that you can get better merge semantics. Rebase and merge become the same thing. Commits can’t somehow conflict with themselves. You can have the system handle 2 non conflicting changes on the same line of code if you want. You can keep the system in a conflict state and add more changes if you want to. Or undo just a single commit from a long time ago. And you can put non text data in an crdt and have all the same merge and branching functionality.

The README of the repo offers a hint:
