Deleting a live flow ends the calls it has out on workers and drops what a removed node still returns, so a node that never returns gives its slot and process back and a late answer no longer recreates the flow's values; a cancel goes through the call's own inbox and is sent after the call's frame, so a service stopped right after starting no longer cancels before its serve
