Answer
To keep the reactive pipeline from flooding a database or HTTP dependency with too many concurrent calls.
Reactive code can create massive fan-out if concurrency is left unbounded. Limiting it is part of reliability design because it aligns the pipeline's parallelism with downstream capacity.
