Real life outages tend to be caused by pilot error, software upgrade
maintenance and software bugs rather than by people removing RSP cards.  In
particular on the ASR9k, you can get reasonably good control plane uptime
with hitless upgrades, but that doesn't help you much if the SMU requires a
line-card reboot.  It also doesn't remove the need for maintenance windows.
