The snapshot-based system requires that the patch order matters which Darcs/Pijul don’t require so long as the patches apply since they commute. This means you can pull in patches from other users at an time in any order & still get the same stable reference. If you apply patches in a different order in Git, you will get a different reference hash & some entity ends up needing to be the centralized source of truth when doing deployments & stuff—which is probably why everyone ends up having some code forge for their code base on a centralized server to “sync” the state.

And with rebase, how are the commits immutable? Seems like MS GitHub found a way to mutably drop commits recently…
