Over the decades, I've had a handful of customers that preferred uptime 
to convergence, because they were measured on that by their boss, 
organization or auditors.

You know - the kind of people that would refuse to reboot a router to 
implement new code, because "Last Reboot: 5y, 6w ago" looks far better 
than "Last Reboot: 15min ago" - those people.

Protocols staying up despite the underlay being unstable means traffic 
dies and users are not happy. It's really that simple.
