Otherwise, we are fetching tasks to block them, and for each task, all dependencies that have a status that that would block the task from running (i.e., it is inconsistent with the task's Dependency.Status field) and have not been marked unattainable will be retrieved. The ignoreDependencyStatusForBlocking parameter indicates whether all tasks that depend on the given need to be updated for a blocking operation (for example, if a single host task group host terminates before completing the group and we need to block all later tasks regardless of their Dependency.Status field).
