PR merged.

https://github.com/openshift/machine-config-operator/pull/822 is still open.

I searched through the last 14d of CI results for log messages that were removed/changed in the PR (https://github.com/openshift/machine-config-operator/pull/822):

- "etcdQuotaGard deployment not present"
- "Node object was modified and not up to date; retrying"
- "Failed to make node %s %sschedulable"


I was unable to find any evidence of those messages.

Additionally, I pulled the machine-config-operator image included in the 4.1.0-0.nightly-2019-06-19-033215 release and inspected the contents of the changed manifest:
