There is the potential to have monitoring systems, and other small agents, running on systems in production. I could see this simply as a stop-gap to prevent Cassandra from being able to starve the system of free file descriptors. In theory, if there's not a proper watchdog on your monitors this could prevent an issue from causing an alert. However, just a potential advantage I could think of.
