Isn't that how the current systems work though? Git inserts conflict markers in the file, and then emacs (or whatever editor) highlights them

The big red block seems the same as "flagged", unless I'm misunderstanding something

With git, conflicts interrupt the merge/rebase. And if you end up in a situation with multiple rebases/merges/both, it's easy to get a "bad" state, or be forced to resolve redundant conflict(s) over and over.

In Jujutsu and Pijul, for example, conflicts are recorded by default but marked as conflict commits/changes. You can continue to make commits/changes on top. Once you resolve the conflict of A+B, no future merges or rebases would cause the same conflict again.

Thank you for the explanation, i did misunderstand! seems like a neat feature
