To be clear, while jj does that, it's entirely local on your machine, and not shared.

Even on my local, that level of snapshotting adds unneded complexity that has very little value.

Additional complexity ? jj just increase the frequency of snapshots. it does not fundamentality the complexity of the system

The one thing I do like about git’s staging area is that it’s truly useful for reviewing a bunch of changes (bulk actions or automated tools). Go over the change chunk by chunk and stage what matters (magit makes that extremely quick.

That could be probably done by jj. But the git’s way is already fine for me.

Yes, jj does make this very nice and easy. It’s the same idea as git, except that “the index” is just another anonymous change, not a distinct feature.

Value is of course subjective, but many of jj’s popular features, like undo, are based on this.

(I actually think it’s tremendously valuable for a number of reasons but it’s fine to simply disagree about that.)

The internal version at least is heavily based on a global commit cloud.

If you give me your commit ID I can immediately print it on my workspace without you having to upload a formal change request.

That’s a feature of jj’s integration with Piper, and is not relevant outside of Google, as neither Piper nor that jj integration is available to anyone else.

That's not a jj feature, but a CitC feature. You can use it on hg workspaces or plain p4 workspaces.
