Is there a reason server.Stop is not called on SIGTERM?

I notice that by default asynq does not respond to SIGTERM except to break the signal listening loop:

Is there a reason not to call server.Stop here? It seems like not calling could result in tasks being lost in environments that don't use SIGSTP (amazon ECS doesn't appear to).
