Discussion Topic

From what I can see in the code, IdleTrackingBackgroundService will check for sessions to clear even if server is configured as stateless - which seems somewhat wasteful if we know that there'll never be an open session to clear. This is probably even more relevant after 1.2.0 which pushes to "stateless by default".

	var timeProvider = _options.Value.TimeProvider;
	using var timer = new PeriodicTimer(TimeSpan.FromSeconds(5), timeProvider);
	while (!stoppingToken.IsCancellationRequested && await timer.WaitForNextTickAsync(stoppingToken))

	await _sessions.PruneIdleSessionsAsync(stoppingToken);
	}
