My reaction: Finally!!! Wait... god damnit!
"Finally!!!" because such a facility is awesome and couldn't come sooner.
"god damnit!" because considering this nugget of brilliance is only going to be released on Fedora later this year there is simply no way of it coming to RHEL 7.
(Small team here so it does help tremendously in the "update management" department if we simply stick to what's available on the standard RHEL repositories... especially since Redhat does an astonishingly good job (in our experience) in ensuring that patches don't end up borking our live servers (and of course replace RHEL with CentOS for our less mission-critical servers)).
