As someone who troubleshoots networks for living, it can't be overstated what value easily understood information has. Normal factors such as lack of understanding of a system, miscommunication, false assumptions, false information, all types of bugs, and operator error already plague troubleshooting. Anything you can do to simplify is extremely important. Little things like being able to read debugs directly out of wireshark can make the difference between solving something between minutes and hours, days and weeks.<p>Unfortunately serviceability is not normally high in the initial product requirements, but I've seen a direct correlation between customer satisfaction in support and products/protocols/designs with good serviceability.
