Requiring that all Stream bulk computations like reduce continuously check for async cancel status between each per-element operation is unlikely to satisfy anyone at all, yet seems to be the only defensible option if we were to support it.

Actually, we already support it. Any per-element lambda supplied to any Stream method can itself do any kind of async cancel check itself, and throw an exception rather than returning a result.

Case closed?
