When to scale an amount of Temporal Workers from 1 per queue

When does it make sense to scale amount of Temporal Workers? Temporal gives a bunch of parameters in workerFactory inside workerFactoryOptions, also we have a couple of parameters to tune for each worker in workerOptions. It looks like you should be able to scale the one worker per queue to handle any load that needed (under the limits of your hardware for sure) and utilize your hardware. When and why somebody should look into spawning N > 1 Temporal Workers inside the same JVM using multiple calls to WorkerFactory#newWorker(useSameQueueNameSeveralTimes) ?

I don’t think there is a valid reason to start multiple workers for the same task queue name.
