Control status will be replaced by job-specific output at some point. Task was not useful anymore with state machine, may reintroduce something similar at a later point, but consider alternatives: - opentracing.io - embedding everything in ctx - activity stack would work easily - log entries via proxy logger.Logger object - progress reporting should be in status reports of individial jobs
