In https://github.com/openshift/origin/pull/22833/commits/50872400c21124bf825b4663ac720106f5aba351 we restored unprivileged access to system:discovery role, which was there in 4.1. We need to revert that change to be compatible with upstream, which fixed this in response to a CVE.
Moving back to assigned as I need to add an e2e test to confirm this never regresses in the future.
There is still a non-trivial amount of work left to do.
Added #1729552 as a blocker for this issue.
