See #540 (comment) with_new_children is being deprecated in favor of replace_children. We need to implement that for all our custom plan nodes.
Implementations might choose to declare fractions of tasks, so that when they get aggregated together (e.g., during ChildrenIsolatorUnionExecs), they do not request a higher task count than needed. When resolving to the final task count, the ceil of the fractional value should be taken into account.
