It sounds possibly useful for a form of "load balancing". You have a producer put onto any of several channels, each with a consumer. If some consumers are backlogged the put will go to one that isn't backlogged, instead of blocking, if there's a consumer available. For a CPU-bound task where the consumer does jobs and the producer hands out jobs, you'd want as many consumers as there are hardware CPU cores, or maybe slightly more. Even if the jobs varied somewhat in size that might keep all the cores busy until there was almost no work left to be done (vs. handing out jobs in round-robin fashion, or pre-dividing the work among the CPUs).
