Hi Dalibor, this ticket is a TestOnly one, which means no action required from devel side (apart from providing devel_ack+) but testing by QA is still missing. So whenever they get capacity for it, they should provide qa_ack+ and it will make it into the next errata and is tested for. Therefore we want to keep this ticket, otherwise the feature is there but we can't (officially) be sure it's working as intended. I'll anyway move this to rhel-7.8.
