Do we need to keep this method if it does nothing?

Yes. BaseScheduler is a base class / klass for schedulers, essentially an interface for all schedulers instantiated and used by SchedulerApp. BaseScheduler.stop_extension creates a placeholder for scheduler cleanup / stop_extension logic that is called from SchedulerApp.stop_extension.
SchedulerApp.stop_extension is a public method inherited from ExtensionApp called by Jupyter Server when the server is stopping.
I implemented stop_extension in default Scheduler in Scheduler.stop_extension to correctly terminate Dask and avoid JupyterLab process not shutting down immediately on interrupt as for example we've seen in Jupyter AI.
