When an async job is running, we sometimes need to know how it was started to distinguish between several types of the job, e.g., post-copy vs. normal migration. So far we added a specific bool item to qemuDomainJobObj for such cases, which doesn't scale very well and storing such bools in status XML would be painful so we didn't do it. A better approach is to store the flags passed to the API which started the async job, which can be easily stored in status XML.
