I agree with your comment if you remove the words "but then" and "other". It's a good idea for orchestration software to detect/avoid unhealthy nodes and enforce the resource limits it uses for bin-packing. It's also a good idea for monitoring systems (by which I mean ones which do alerting and visualization) to track memory usage and pressure stalls. [1] I wouldn't say swap is a substitute for these in any way. A swapping machine is an unhealthy machine.
