RHEL6 scl-utils contain a bunch of bug fixes and features that didn't make it to RHEL7 because of shifted time schedules. To address this bug, the necessary changes must be done in RHEL7 to make scl-utils synced in both RHELs feature-wise.
This bug has been closed as CURRENTRELEASE due to delivery of the fix in a z-stream. As the component is not on ACL, the fix is currently included in y-stream as well.
For more information please see the zstream process documentation:
