Not sure where you’re going, but my take is that yes, the times for calling servers individually are over.
But we’re still touching the belly of our distributed systems with very pointed tools as part of the daily workflow. That’s how accidents happen.
The analogy is clear IMHO; just as we’ve long stopped fiddling daily with the DRAM timings and clock multipliers of the Galadriel and Mordor servers, we should consider abstaining from low level “jumper switching” on distributed systems.
Of course, this also happened thanks to industry introducing PCI and automated handshaking...
