At certain points its not “useful”, but mandatory to simply keep functioning. Even small failure and change rates are untenable as device and port counts increase to Very Large numbers. How do you maintain millions of devices? Think on the order of hundreds to thousands if automated remediation workflows for every exception that requires a person in network operations to intervene. Once you move beyond simple deployment and break/fix theres a huge step function in the change count as well. Networking is far behind on concepts like “continuous deployment” or software updates its not funny. And unlike everyones favorite stateless container of the day networks take coordination to perform intrusive maintenance.
