Here's a summary of XDG_STATE_HOME from [1]:

    The $XDG_STATE_HOME contains state data that should persist between
    (application) restarts, but that is not important or portable enough
    to the user that it should be stored in $XDG_DATA_HOME. It may contain:

    - actions history (logs, history, recently used files, …)

    - current state of the application that can be reused on a restart
      (view, layout, open files, undo history, …)

For example, I've seen history files end up in the wrong XDG directory such as XDG_CONFIG_HOME.
