The server doesn't care about users, only session ids, and session ids are generated whenever you refresh the browser (although you can set your own ids if you're using the REST api or the session name input field in the GUI). It might be good if a user is managed by the server so previous configurations and such are available (with versioning) and can be selected and updated instead of requiring all of them to be uploaded every time.
This can be especially useful for manual adjustments, so the server can remember them for you.
